Oh My Zsh adds bloat

I use oh my zsh for exactly one reason: I can get a good shell experience out of the box and immediately start working on stuff productively, whether it's a new machine, a new remote host or a container.

I could spend hours figuring out all those things, bit I'd rather use that time for something more important.

> I could spend hours figuring out all those things,

This post is explaining how to set up those things. Less than five minutes to read.

> Less than five minutes to read.

OMZ is still easier to set up consistently. That’s why we use it.

If the concern is the bloat of OMZ then make FMZ - fast my zsh - that is just as quick to set up and doesn’t add “bloat”?

I won't spoil the article, but if you read to the end you'll find out what this "FMZ" project is called.

Can you spoil it for me, because I read it to the end and saw no mention of such a project. Unless you are referring to the DIY approach the article suggests.

Somewhere else in the comment thread Zim (zimfw) was mentioned which after reading their website sounds pretty much like that.

That misses the point. I don’t even want to think about any of that stuff.

It’s a single command to install oh-my-zsh. I can fire it off, check Slack, and come back in 5 minutes. If I have to take 5 minutes to setup it up, I’m just not going to do it.

Caring enough to read a blog post and comment on hackernews, but not enough to copy/paste the changes from the blog post is a very fine line.

Not sure what your point argument is.

Their point is that what you complain about as "time consuming" is not time consuming at all and that you consumed more time reading the post and commenting on HN that actually installing starship.

In your defense I must say I installed starship ages ago but still not migrated to it from powerline-go because I'm lazy.

This is common low-quality internet arguing ("you care enough to come into this thread but..."). You can avoid this by keeping in mind that different things are different things, and analogies have many holes by default.

Less than five minutes to read but how long to set up my own? The author only showed what he needs/prefers ("Here is my config for starship"). I'll need to navigate the documentation of starship to figure out all those options, which defeats the purpose. Their config documentation (https://starship.rs/config/) already gives me headaches.

And from the article

> Because cloud services are available globally, I've disabled them.

That's some bad defaults right there.

> When you run a command, it also shows how long it took to execute.

No I absolutely don't want this thing done by the author. Now I am fully in the "customize my config" territory.

Also, most of us are unlike the author, and 0.07s vs 0.38s startup time means no difference.

I think the point of the previous comment has been more than clear enough.

> Also, most of us are unlike the author, and 0.07s vs 0.38s startup time means no difference.

That's quite likely a workflow thing. If you are popping up new (transient) terminals frequently, then a ~400ms wait time for each adds up and makes the entire machine feel really slow. I'm willing to wait extra half a second for a new terminal -- once -- after I've changed my autocompletion configs (rebuild + rehash takes a while), but if I had to wait for that long every time I hit Win+enter and wait for the terminal to become active, I'd be irritated pretty damn quickly too.

You get conditioned to immediate responses pretty fast.

Yeah but you can use something like zim that is better than omz but still easy. The shell starts so fast with zim and it is a breeze to set up

Exactly. The popular culture has bad picks. We can be low effort without necessarily being 100% unselective! No taste is not mandatory! Just the littlest bit of trying & listening to our peers can make a better world.

There's so many better non-shite alternatives. Just one: Zim aka zimfw is one. It's just so sad that there's such a negative creep energy towards "I tried nothing and did nothing and this is where I am". Bad hacker bad. You deserve no voice.

People should be encouraged to play and explore. I landed on Zim eventually, but it's far from universally installed on my machines.

Try https://starship.rs then. Starship gives you the same "drop in and go" experience but without the 200ms+ prompt lag. One curl -> one line in your rc file, works on zsh/bash/fish/whatever.

Configuration is straightforward and easy imo: https://starship.rs/config/

Give it a spin, I think you won't regret it.

Oh my zsh makes installing extension so easy, just edit .zshrc and add extract, fzf, z, etc. To the list of plugins

What? You still have to install the binary via your package manager. Most OMZ plugins are basically a bunch of shell completions or aliases.

Some are built in

Never heard of this, looks pretty good. Are there any community themes based on starship like powerlevel9k/10k?

It requires a nerd font.

starship is great. I use it with a powerlevel10k fallback in my dotfiles for systems, starship is not installed yet to not break the shell entirely.

Starship is a single binary, pretty easy to carry around even the first time you ssh somewhere.

I'm totally aware... However p10k is the thing I used before so fallback was a low hanging fruit.

I'm so glad I switched to fish, I'd rather have genuinely good settings out of the box rather than endless configuration, and honestly it's much better out of the box than any configuration I've ever had.

Only drawback is that it's not POSIX, no issue for me, but maybe for people who have a lot of muscle memory with bash.

Fish is just excellent out of the box. It's a little tragic how path dependent we are on flawed terminal experiences designed 40 years ago.

I've been using fish for nearly 10 years.

First, there are some ways to make fish more compatible with bash.

If you want to do some shell scripting in fish, or running other people's shell scripts (or commands) this may aid you since you wouldn't have to port them (or take less time to port them over).

You can achieve this with a plugin system such as 'oh my fish' or 'fisher'. But, as always, it adds complexity (and bloat :P), you'll need it on every fish shell (including remote systems), etc.

It is a bit akin to having nvim with plugins versus being able to use vi. Sometimes, you're going to need to be able to use the latter.

Also, to people who recently adopted fish: fish has been made more and more compatible with bash throughout those years.

FWIW, I use fish with starship these days.

When I'm in fish and I want to run a bash script I just... call it with bash :-)

./script.sh

and script.sh just starts with #/bin/bash

I'm simple

This wouldn't work if the script is meant to be sourced (to set environment variables) isn't it?

No, it doesn't.

The way I actually have things setup, in case it helps. I don't change my default shell. I actually default to pretty much working within tmux. So, I kept my default shell to what the OS brings, then in my tmux config, I have,

    # set shell
    set -g default-shell /opt/homebrew/bin/fish

This means, that when I start my terminal, it drops me to zsh (macOS default). Then when I run tmux, it opens fish. The nice thing is that I inherit the environment of zsh.

I have my .zshrc and my .bashrc sourcing a .shellrc file which contains most of my env stuff. This keeps random utilities that write to .bashrc and zshrc working within fish too.

If I use fish, I want to make use of it, and that means I will want to convert scripts, or simply learn to write scripts compatible with fish.

Shell scripts from third parties stick with whatever shell they were written for (ie. /bin/sh or /usr/bin/env bash), and commands copy/pasted from the internet are either quickly executed with bash (one-off) or ported over. Because I like to have such in my history (fish is configured to use atuin), I want to keep using the same shell, so I try to stick with fish. If I cannot convert a command (usually a bunch of commands) to fish, it is PEBCAK and a learning curve/experience.

As for tmux, that is solid advice, because it also allows to stick with a shell which is known to work. I've come to like zellij with alacritty, with zellij the option is default_shell. But now that I use ghostty, I don't use a terminal multiplexer locally any more; only remotely. And there I still use tmux.

It’s only takes a second to run a child bash shell when you need something posix

After 10 years on zsh I finally switched 6 months ago and I haven't looked back. If I need POSIX, I'll just run scripts with the right shebang or pipe it to sh.

For POSIX: I leave Bash as the system shell and then shim into Fish only for interactive terminals. This works surprisingly well, and any POSIX env initialisation will be inherited. I very rarely need to do something complicated enough in the REPL of the terminal and can start a subshell if needed.

Fish is nicer to script in by far, and you can keep those isolated with shebang lines and still run Bash scripts (with a proper shebang line). The only thing that’s tricky is `source` and equivalents, but I don’t think I’ve ever needed this in my main shell and not a throw-away sub shell.

I often write multi-line commands in my zsh shell, like while-loops. The nice thing is that I can readily put them in a script if needed.

I guess that somewhat breaks with fish: either you use bash -c '...' from the start, or you adopt the fish syntax, which means you need to convert again when you switch to a (bash) script.

I guess my workflow for this is more fragmented. Either I’m prototyping a script (and edit and test it directly) or just need throwaway loop (in which case fish is nicer).

I also don’t trust myself to not screw up anything more complex than running a command on Bash, without the guard rails of something like shellcheck!

I used to do it this way, but then having the mentally switch from the one to the other became too much of a hassle. Since I realized I only had basic needs, zsh with incremental history search and the like was good enough.

I don't care for mile-long prompts displaying everything under the sun, so zsh is plenty fast.

I have been using fish for 10 years now as my main shell and it is just perfect.

I tried fish for a while but as someone who heavily used bash before I couldn't get used to the new language. I also didn't feel they the language was much better than bash, at least for my usage. But I loved the default automatic coloring of arguments, underlining of files, etc.

Later I found fizsh, which I love and still use as default shell now. It's basically a configuration around zsh adding the colors, completions, and other good stuff inspired by fish to zsh. Can really recommend it for those who are used to zsh or bash but want their CLI to be more readable. Colors especially help with big command line arguments to show where they start and end, and keeping track of complex stuff like loops and conditional logic in your commands.

fizsh sounds really cool, but the last commit was 7+ years ago. do you run into any issues? https://github.com/zsh-users/fizsh

I never noticed any issues, actually. I guess the zsh base is solid and stable.

I'm surprised Starship is so popular. It's missing really basic powerlevel10k features like empty segments. If you look at some examples:

https://starship.rs/presets/gruvbox-rainbow

You can see that when the segments are empty, they still appear as a 1-width segment, rather than entirely disappearing.

It also makes you configure many things by hand. powerlevel10k has an interactive wizard that lets you design your prompt one option at a time (do you want a nerd font? do you want it one line or two? etc) but Starship makes you manually write escape codes if your preferences don't match one of the presets.

No judgment, but I do wonder what people like about Starship that makes up for these things.

Starship allows empty segments, I in this specific case it's just how the preset/theme works as it uses the Unicode character as separator and it needs to set the background and foreground colors depending on which modules is surrounded by

Every preset with powerlevel10k-style segments don't support hiding empty segments. Look at Pastel Powerline, Tokyo Night, Gruvbox Rainbow, Catppucin Powerline...

https://starship.rs/presets/#pastel-powerline

I tried making my own and the config TOML syntax isn't expressive enough to support hiding empty segments.

You're right that it's the thing with the Unicode character as separator, which all the alternatives handle just fine: powerlevel10k, tide, oh-my-posh... it's just everyone seems to love Starship, and that's what confuses me.

Also oh-my-posh supports transient prompt and AFAIK starship.rs does not.

"Transient prompt, when enabled, replaces the prompt with a simpler one to allow more screen real estate." https://ohmyposh.dev/docs/configuration/transient

Here is my config for oh-my-posh https://github.com/rofrol/dotfiles/blob/master/.config/oh-my...

I tried using Starship, and it’s clearly faster than Oh My Zsh, but my issue was that I relied on some useful Oh My Zsh features that I didn’t know how to replicate in Starship. One of these is history filtering - for example, when I type source and press the up arrow, I only see previously run source commands, which makes it easy to find what I’m looking for. I tried to get this working in Starship, but had no luck.

I have never used Oh My Zsh, but I use Atuin to do this and it works excellently at that. You can even make it filter by what folder you're in and whether you want to search only this session or host (you can sync shell history across hosts). It never occurred to me that this is something I'd want from a shell prompt, which is what Starship is.

Control r. This is a zsh feature not a starship/oh my zsh feature

mirzap was probably using some omz plugin to do that, so if starship fully replaced omz, that functionality went away, too.

I think that's just a standard readline functionality. It's available on bash, out of the box.

Absolutely and in zsh too, out of the box. It kind of blows my mind that people think they need all this additional bloatware for things which have always just worked (at least as far back as like 96 or so which is when I started using Linux) but it wasn’t new then.

Wait till people learn they can use rlwrap to get the benefit of readline even in things like commandline sql clients, which often lack this.

I think convenience inherently comes with bloat. This is true for many things in life. Most people use cars simply to drive to work and back, yet they don’t use 90% of the features sold to them by salespeople.

Ob Linux it's actually handled by inputrc

Oh my god! How did I not know about this! Thank you! Are there any other useful tips like this one?

You are most welcome. Probably hundreds but I don't know what you don't know. It's worth learning some old-school command-line history fu as well because that is often useful. I've written up some things I have found helpful here[1]

One thing which is not in the writeup but should be (and I mention it in a sibling thread) is "rlwrap" which is a readline wrapper which imbues whatever program with readline editing and history niceness.

So say you have to use some crufty cli like a sql cli or something that doesn't have commandline editing or history. You run "rlwrap horrible_sql_cli" aaand now it does. Really helpful.

[1] https://www.uncarved.com/articles/unix/

check atuin for history search

I haven't checked out starship yet, but if I understand what you are using, that is Zle functionality. It's part of OMZs configuration (here: https://github.com/ohmyzsh/ohmyzsh/blob/master/lib/key-bindi...) but doesn't use other OMZ features.

I don't know if starship is still using Zle. If so, this should be possible to configure without OMZ.

Oh thank you, I was looking for this. Will try it.

From what I can tell, this doesn't nearly fill the gap that OMZ occupies

Nice history, command auto complete, and similar beyond just the looks, out of the box

I'll second this. I've had a really pleasant experience using Starship across development environments.

Just tried Starship, even though it wasn't the first time I'd heard about it. I would not say it is a 'drop-in and go' experience. Let me explain.

After installing and adding it to my bashrc, I was wondering was those version numbers and cloud symbols meant. Turns out: Since NodeJS and Python were installed, it found a good idea to print the respective versions. I could not care less about those versions. The other part was that it thought that I would like to see my AWS region. Well, I mean, I have built something with AWS a few years back, and the config file for that still exists, but no, I don't want to see that region every time I open a shell. Finally, the default is to have the prompt in a new line. I think when you have a long prompt that makes sense, and it might also be a taste thing. However, the documentation has this example at the beginning about newlines:

  # Inserts a blank line between shell prompts
  add_newline = true

So I thought `add_newline = false` should do the trick, but it didn't.

Luckily, the AI (GPT-5.2) was pretty good at explaining and giving instructions for changing things. So after 30 minutes, everything was understood and configured to my liking. I like the result, but the default was pretty weird.

Also oh-my-posh supports transient prompt and AFAIK starship.rs does not.

"Transient prompt, when enabled, replaces the prompt with a simpler one to allow more screen real estate." https://ohmyposh.dev/docs/configuration/transient

Here is my config for oh-my-posh https://github.com/rofrol/dotfiles/blob/master/.config/oh-my...

I've spent few days and got some basic zsh settings adjust for me. Since then I'm mostly using zsh with very little configuration and I like it a lot. Yes, it's a steep curve, but I'm spending all my life in zsh, so I think that was good time investment for me. In my experience default zsh settings are good enough and require very little customization.

I just use fish shell. Way easier.

https://fishshell.com/

I recreated my several hundred line + several plugins zsh config in a few dozen lines of fish and one plugin (fzf.fish), about 8 years ago. It’s been a joy to use.

Biggest problem being not being able to paste much of the complicated code found online. You can save it and run it via bash command though.

oh my zsh can recreate much of the fish functionality while maintaining good bash interoperability.

This is the most common complaint I see for switching interactive shells to fish/nushell, but it's not a problem in practice. You don't ever uninstall bash, so if you've got a command to paste:

  bash <enter>

  <paste> <enter>

  exit <enter>

Tada!

Exactly this, couldn't be easier. Heck, I run into this all the time on macOS whenever an LLM gives me a Bash one-liner that for some reason doesn't work with ZSH. It's easier to just pop into Bash than analyze and adapt that command line to ZSH.

> couldn't be easier

Except for the single step workflow: <paste> <enter> like you do on POSIX shells?

Couldn’t be easier to use another shell. As in: it’s hard to imagine making it even less complex. Which means it’s no burden at all.

Do you get it now?

FWIW if you're on a machine where you're allowed to use non-default configs like oh-my-zsh, you could also just copy over your own custom config. It seems like you're implying the alternative to using oh-my-zsh is to rewrite your config from scratch every time or use the default. It doesn't quite add up to me. If you craft a config file of your liking one time, then back it up somewhere, track it with git, whatever, you can keep making use of that config across other machines. I just set up a new personal machine recently, grabbed my dotfiles, now it's the same familiar feeling as my other machine.

> just copy over your own custom config

That already defeats the purpose:

I don't want to copy things around

I never spend time crafting a custom config

Crafting a custom config is right up on the list of things I enjoy. Right up there with creating new characters in video games that allow lots of customization.

Hmm, weren't dotfiles invented just for that reason?

I'm joking but on a more serious note, installing a shell as a default shell seems more complicated than copying over your .bashrc

    more complicated than copying over your .bashrc

In case you weren't aware, MacOS uses zsh as the default installed shell. The bash version that comes with MacOS is some ancient 3.x version, from 2005.

I think you where trying to say something and then stopped just short of actually making your point. Please continue.

Just that it would be `.zshrc` since zsh is already the default shell in the context of this post unless you enjoy a mid-2000s existence and none of the nice bash features of this generation (in which whatever `.bashrc` you've crafted is likely broken by time passing).

Maybe I'm underinformed, but I don't personally know any Linux users who convert to zsh, instead opting for fish or something else (oilsh? nushell?).

zsh has similar files that can be copied over to other systems.

I stopped using Oh My Zsh for exactly one reason too: It was so freaking slow it had a noticeable effect on my shell and my mood. It frustrated me that I had to stop and wait every time I opened a tab.

So I removed it, then continued using Zsh and whenever I missed something from before I looked up what it was and installed the plugin easily with Homebrew. The whole process took under an hour. I realised I only needed two or three plugins.

Now my shell is fast, without unnecessary bloat, and does what I need. I’m much more productive and happier, and at the end of the day I don’t really see what’s more important than that (within the scope of the conversation).

One man’s bloat is another man’s feature.

just install fish then

You really only have to go through that once and it's a good learning experience.

I will have forgotten almost everything by the time something inevitably breaks in a few years. Unless I am constantly recalling the knowledge and applying it, I don't find it worth it. And I _don't_ want to be constantly recalling this knowledge. I want it to just work.

OMZ has been working steadily for me for the past 8+ years. Autocomplete, syntax highlighting, and a concise prompt--really all I need.

I mean you learn things about the shell ans shell scripting in general which you do retain. Also shell config is one of those rare things that doesn't "inevitably break." The only stuff that breaks are related to program settings which omzsh isn't going to handle anyway. You end up learning a bit and have a much lighter config. Case-in-point, you had to spend some time combing through and learning all the aliases it defines you when you could maintain a small few that you actually want. Also, zsh has plugins natively.

Exactly why I switched to fish. Fish doesn't come preconfigured exactly how I would like, but it's close enough that I just grew accustomed to fish defaults and have no trouble with it now, and no longer give any thought to shell configuration.

The additional upside of this approach is that you can also quite easily install fish on any host and it won't need any configuration to match what you're already used to

Really curious what is missing from the default configuration in your setup.

If I'm feeling really fancy I may enable vim bindings and add the fuzzy find plugin, but plain fish is so good on its own.

Best shell UX for minimal effort is: fish shell + starship prompt.

Using starship for the prompt provides many pretty UX improvements (showing current git branch, language version, kubernetes context, etc.).

Not OP, but I just switched to Fish and immediately had to find community plugins for both `z` and `!!`/`!$`. Yes, Fish has alt+up/down to navigate arguments, but I have 15 years of muscle memory pointing to `!$`.

Totally agree. Fish out of the box is super performant, lots of tools ship completions for it, and the UX is just great. Only recommendation for people new to fish is to read the keybinds thoroughly. I convinced an eng on my team to switch but he was using it like sh: not using tab complete, shift+arrows for partial complete, etc. Slowed him down a ton.

> For Vim users, I also suggest enabling Vim mode in Zsh. It makes editing commands much faster.

I am also an avid Vim user but I disagree. The default readline is perfectly fine for single line commands (you do have to know your way around some basic commands though C-a/u/k/l/w...). To edit long commands in $EDITOR you can always do C-x C-e in bash/zsh (M-v in Fish). As a matter of fact everytime I pair program with my colleague I always think he is editing those short commands slower than I would have because he has to change modes all the time.

I like to re-add the readline binds after enabling vim mode, and then I only leave insert mode occasionally. C-x C-e really is great, though, I think I do tend to reach for that if I need to do a big edit of a one-liner.

> you can always do C-x C-e in bash/zsh (M-v in Fish).

Thanks I didn't know!

Changing modes is a single key stroke away. That's hardly a reason to be slow.

Readline settings depend on what you're already used to. If you're comfortable with vi key bindings, then being in normal mode, navigating with `w`/`b`, deleting a word with `dw`, deleting up to a quote with `dt"`, etc., are all done with muscle memory, and should be much faster than learning the equivalent Emacs bindings, pressing unintuitive key chords, or opening the command in an editor. I don't like opening an editor since it's an interruption, and it hides the output of the previous command.

I wish I could have the full power of Vim in my shells. For example, I miss the delete between characters binding. `di"` or `di'` are great for modifying argument values.

I can't believe it, have been an zsh user for a long time and didn't know this trick until now

Like many other people, I use oh-my-zsh for default setup and that's it. I literally use a single plugin for git and very actively autoload my custom functions to avoid startup delay. With my 384 line config and oh-my-zsh on, here are the results:

$ hyperfine -N "zsh -lc 'exit 0'" "zsh -c 'exit 0'"

Benchmark 1: zsh -lc 'exit 0'

  Time (mean ± σ):      54.5 ms ±   6.3 ms    [User: 10.2 ms, System: 14.3 ms]

  Range (min … max):    38.1 ms …  64.9 ms    78 runs

Benchmark 2: zsh -c 'exit 0'

  Time (mean ± σ):       6.5 ms ±   1.4 ms    [User: 0.8 ms, System: 1.3 ms]

  Range (min … max):     3.9 ms …  14.2 ms    424 runs

It's crazy how their startup time is 380 ms, and I suspect something else might be the reason, not just oh-my-zsh

Trying doing the benchmark in a git repo.

That's where I actually did it, by coincidence

You should try extract, z, and fzf

I think `zsh -l` start a login shell, which does not load zshrc so oh-my-zsh don't get initialized. Try `zsh -ic exit` and it should load zshrc before executing exit.

That said, the time of `zsh -ic exit` isn't really meaningful metric for measuring the performance of an interactive shell. See https://github.com/romkatv/zsh-bench#how-not-to-benchmark for details.

Valid points, I learned something new today. Thanks, you were right. If using -ic flags I am getting around 300 ms... Interesting how I never noticed, guess I don't open many terminal during the day

Better way to benchmark zsh startup time is with zprof. Add this to your ~/.zshrc:

    zmodload zsh/zprof
    .. rest of your zsh config ..
    zprof

And then restart terminal.

For anyone who cares about zsh startup performance, `zsh4humans` by `romkatv` (author of powerlevel10k) is worth a look: https://github.com/romkatv/zsh4humans

It achieves instant startup by rendering the prompt before the full shell initializes. Since adopting it, I am done fiddling with my shell config and the fact that `zsh4humans` is in maintenance-mode is actually an advantage as it keeps me from wasting time refactoring `zshrc`.

I switched to fish shell with star ship. Fish has autocomplete and syntax highlighting out of the box which is quite neat and the main features I use in omgzh so fish was a safe choice for me

https://ruky.me/moving-from-zsh-to-fish-nixos-darwin/

Also, you probably don’t need to customize it at all, it’s more than good enough out of the box.

Fish is also not POSIX which has always been its, and my, issue. I use zsh+starship and my own very minimal init stuff+zsh autocomplete and syntaxhighlihg plugins. It’s not a perfect setup. I wish fish would “just work” but it doesn’t. Frequently I had to look up for “workarounds” for my setup. 25 years in, I think I got it and i just keep my zshrc and `machine-init.sh` on point for my-own-style-experience. I think a lot of that could be simplified with fish+starship, but it’s just not there.

> Fish is also not POSIX which has always been its, and my, issue

Could you give some examples of issues you encountered because of that? I've been using fish for about 8 years now I can't remember an instance where that was a problem in interactive use.

Same here. More than 5 years with fish and it’s been like 5 times when not-POSIX was an “issue”, which I’ve been solving by temporarily entering bash and rerunning the command there.

Issue is the cognitive overhead to know 2 distinct shell languages. One you use, and one (almost) everyone else uses. If later isn't of your concern and Fish is all you interact with then no issue whatsoever for interactive or/and scripting use.

Not to be funny, but is POSIX scripting even still relevant? It's well understood that they should only be used for quick and simple tasks, and anything more serious or demanding should be done using something like python instead. But these quick and dirty tasks are very easy for LLM coding agents to do in python. I used to have dozens of shell scripts, each no more than tens of lines long, in my ~/bin/, but I had an LLM rewrite all of them in python, adding proper argument handling, --help messages and error handling too in the process. I sincerely don't think I'll ever write another bash script again.

Do you know how many CI/CD pipelines run on shell scripts?

Another example is small utilities. I wrote one to login to MySQL DBs at work. We have to use Teleport, which I dislike, and it has MFA. So I made a small SQLite DB that has cluster names, endpoints, and secret ARNs (no actual secrets, only metadata), and then wrote a shell function that uses fzf to parse the SQLite DB contents, then ssh tunnels through an EC2 with Teleport to the selected MySQL DB, using expect with a call to 1Pass to answer the password request, and then picks the first available port >=6033 to connect the mysql client. It also tracks the MySQL DB : port assignments in the SQLite DB and waits for the client to exit so it can tear down the ssh tunnel. The only input I have to do beyond selecting the DB is answering a push notification on my phone for MFA.

> replacing 10-LOC shell scripts with Python

The startup time would drive me insane. I love Python, but it’s not great for stuff like that, IMO.

I write all my scripts in bash. I'm not learning a new language.

That's not a problem since it's available and when #/bin/bash or env bash is there, it just works.

My bash scripts are stored in a folder on my PATH, so it all just works.

For me it’s always been an inability to “copy this command from stackoverflow” (or in the modern day, it’ll be copy this from ChatGPT) into your shell. Maybe it’s better now, but the last time I seriously gave fish a chance was 2014.

Also one of may main use case is documenting things other developers can do to make their life easier. There are handful of things where zsh behaves differently than bash. And while those handful of thins are not even a POSIX or shell things, they often come up.

The reality is, every day I’m fighting with “developers” who don’t know what the difference between AWS, Linux, and bash is. Throwing “fish” into the mix seems like I’m just being obtuse for no reason. I have sept hours trying to explain to some dumbass that git-bash on windows is not the same thing as Linux only for them to call me “oh he really cares about ‘bash’”-guy. While claiming they are “Linux developers” as they use macOS.

I confess I don't really get this. Fish and Bash are different languages in the same way that Ruby and Perl are different languages. And if I want to run a Perl script, I don't try to run it in a Ruby interpreter, and I don't get grumpy at Ruby for not being source-compatible with Perl.

Which is to say, if you need to run a Bash script, run it via `bash foo.sh` rather than `./foo.sh`. There's no need to limit yourself to a worse shell just because there exist some scripts out there written in that shell's language.

There's nothing even preventing the second form from working either. Just put the right shebang at the top of the script and it'll run through that interpreter. I've been on fish for a decade, but still write all my shell scripts in Bash. It's never been an issue.

Yeah. I used zsh for decades, invested a reasonable amount of emotion and time in my config but swapped to fish last year as a sort of January trial and it stuck.

It's not perfect, the lack of HEREDOCs are annoying sometimes, and no background-able blocks (eg `{x}&`) means you can't async things as easily in scripts.

Zsh has a lot of advanced stuff (at least for a shell) that can deliver pretty complex scripting such as throw/catching, mountains of variable flags and switches which I do miss when I write fish scripts but really -- I've abused them a lot over the years and now days I would be more likely to just use a "builds to a single binary" language.

I will probably swap to nushell when it gets a bit more stable (in my experience it's runtime is stable, but it's feature set / command names are still shaking out. I really like it's general ideas though in terms operating on structured data.

You only notice this stuff if you use shell very often, and practically live in the command line. Since I started my career I've been using omz and a fresh install is always snappy but over time it starts getting slow.

Debugging/profiling why it's gotten slow has mostly been an uphill battle for me. I tried using zprof which pointed that compdef and compinit were culprits. I tried changing my config to calculate compinit only once a day since most people reported it to work, but it never worked. This kind of stuff pokes and stabs at you endlessly.

OMZ being shell, and being a maze of a codebase, I couldn't track down if and where compinit was being called from even after the config change above, because all profilers pointed to the possibility of compinit being called twice.

I gave up and started using barebones zsh + starship because I do need a good prompt. Yet the issues persisted.

I recently started using fish + starship on my local machine so that I could evaluate it before committing to it at work. It's the fastest shell so far (maybe because its new, I intend to find out).

My only painpoint now is I have a bunch of utility functions I've maintained in bash that I need to port to fish because of the posix incompatibility.

OMZ is absolutely bloat.

I installed oh-my-zsh back in early college some 15 years ago, before zsh was even the default on macs, and it is so good I’ve never felt compelled to experiment or try any other shells terminals or configs. It’s the first thing I install on every new computer.

I switched to zim years ago and found it has all the features that I need but is much faster and I think easier to install (though I haven’t installed either for some time).

https://zimfw.sh/

Fast as sin, and one of the most flexible installers systems. You can point it at an incredibly diverse array of different things to install, in different forms, with different urls, and it will just do the thing.

Zimfw definitely has it's own ecosystem, plugins which are zimfw capable. But it's remarkably versatile at bringing in zsh code. Most plugin-systems are pretty ego-centric, demand specific implementations, and zimfw stands out not just for it's ridiculously impressive speed & handling, but for it's versatility too.

Zimfw rocks.

> The main problem with Oh My Zsh is that it adds a lot of unnecessary bloat that affects shell startup time.

Wowsers!

That +0.5 seconds delay will kill cats everywhere. We must microoptimise the startup time of shells!!!

Or ... we could simply use bash and KDE konsole with, say, 10 tabs. That setup works for me since ages; admittedly I use bash just as a wrapper for simple actions as well as calling a gazillion of aliases and mostly ruby scripts that do the real job. But damn I never knew there were guys who were concerned with +0.5 seconds delays caused by oh-my-zsh. The bloat! Oh my godsers!

Plus, how many shell can one individual open in a day ? I'm doing that once per day on a good day, maybe twenty if I have a lot of unplanned work on subprojects that needs to be done concurrently with my main task.

Sometimes hundreds per day. Tabs come and go here. People have different workflows.

Yesterday just shy over 50, according to entries from `login` in the system log.

I do launch multiple interpreters just to get a fancy coloful cowsay on each launch. Which involves the fortune program, lolcat (via ruby) and cowsay itself (via Perl). I probably should optimise that into a single C binary for better startup times! :)

The problem with long startups is that they break the flow. I live in CLI. I open and close terminal windows all day long, sometimes just for quick 2-3 commands to check something. 100 new interactive shells a day is my guess. I already know commands to run, my fingers are ready to type, they already pressed the keys ti spawn a new shell and now they have to stop for 500 ms. Repeat these 100 interruptions every day and you get the death by 1000 spoons.

I don't use oh my zsh, but on one laptop zsh took 600ms to start. I narrowed it down to a strange "bug": adding even a single empty file to the custom fpath caused the slowdown. It bugged me so bad that I decided to try fish again, but this time for real. And this time it stuck with me. I like its architecture (defining functions to change its look-and-feel - great idea!) and of course its 32 ms startup time.

As another commenter, I'm probably at 100s per day.

A reason is that I use i3 workspaces, with each workspace being for different tasks, so I don't want to reuse a terminal that has another context.

One issue with keeping a single shell is that the history is full of irrelevant stuff. If you run commands that take a while and print a lot of output, you want it to be as clean as possible. If I want the beginning of the command, I can scroll to the top, and I don't end up with some unrelated output.

I also take quite notes in vim everywhere, often next to long-running commands, using tmux.

For terminal-centric workflows, one ends up needing to open dozens of shells throughout the day.

Starting one command, realizing you need info from a previous command, often the fastest way to get that info is to open another terminal and start typing and the copy-pasting the relevant piece of cmd. Or needing the output from another command that's scrolled up in a window. In general you end up with a mosaic of tiles each of which is holding key information. So you inevitably open a new tab to make use of the information in the other 3 or 4 windows.

Shell startup is mainly not about waiting for a few terminals in abstraction, but about the way each shell is just a small piece of a longer live workflow and waiting a second for a shell so that you can fill in a piece of a command feels terrible. I think nushell will help cut down on this unpiped inefficiency, but it's usually much simpler to manually glue bash commands together than to parse text output and pipe.

I couldn’t help but think this as well. I understand wanting software that feels snappy, but this is hardly a problem. Instead of trying to convince the reader that we should care about this, it would be nice if the writer admitted this is an inconsequential personal preference.

For command search I've replaced regular search and fzf with atuin. Works especially well with multiple hosts.. https://atuin.sh/

EDIT: The OP fails to mention zsh profiling: zprof. I discovered that atuin is my biggest waster at the moment with like 20ms and rest of the stuff I could clean up.

I'm using fzf and it's amazing. What does atuin bring additionally? Looks very similar

Atuin also has syncing and backups though I've never really felt the need to use it. I prefer keeping histories separate and when I need to share shell commands I just do the usual methods like putting it in a shared text file, send it to myself on a chat app or just looking at the command and typing it out

Yeah. It boils down to preferences. By the way, there is also an option to search only in current host and current directory as well (+current session).

I use atuin for the shell history as it seems to know when I've run a command in one tab/split while another is open where fzf doesn't seem to sync it all the time. But I still use fzf to find files.

(Bonus, I use Zoxide to replace the alt+d cd shortcut as it's much faster, and use https://github.com/Aloxaf/fzf-tab for tab completions in the terminal to become fuzzy, very very useful)

>it seems to know when I've run a command in one tab/split while another is open where fzf doesn't seem to sync it all the time.

On my machine this is handled in zsh, not fzf (but then fzf still benefits). You can configure your shells to sync without exiting. You may need to run one command (or just hit enter with nothing typed, maybe) for the shell history to catch up, but then it should all be there. Relevant options:

# share history among terminals

setopt share_history

# append to the history instead of overwriting

setopt append_history

# append to history incrementally instead of when the shell exits

setopt inc_append_history

I think finding out about this is why I originally switched from bash to zsh several years ago.

Yeah I believe I have these already configured as such, it was that atuin didn't require me to press enter again but thank you for sharing

Dunno.

I have 90 lines zsh config with 3 plugins (compinit, vcs-info, edit-command-line) and startup-exit sequence takes 0.32s.

You learn very quickly where the lags come though when you work on a big old repository (I learned this on Emacs source code) where getting current branch for jujutsu takes ~5 second. Git is faster in this regard but it still is ~0.3s

I'm not fan of starship (I don't use fancy command line variables in general) but many of those issues can be dealt with awesome bkt caching utility [0]. Instead of live reading just let bkt cache it with long TTL with eager async refreshes. My guess is that Starship does exactly that.

[0]: https://github.com/dimo414/bkt

https://grml.org/zsh/

Simple, sensible defaults.

Ships with the Arch Linux installation ISO.

Yes, that's also what I use. Always found oh-my-zsh a little too much and too hipster-y for my taste.

I moved from oh-my-zsh to grml ~10 years ago, and I've enjoyed it - it's got good defaults, is extensible (I've added custom stuff to handle how I manage directories for work things) and the single-file nature of the defaults makes it super straightforward to put it onto a new machine (ie a server) without then necessarily needing to do any extra tweaking

Or simply use fish

Nowadays I just use fish with the out of box installation and it fits all my needs.

Craziest thing: You can still script in bash/zsh even if you use fish but you can't always copy-paste from StackOverflow.

The problem is that I forgot (if I ever knew) bash.

I can write fish, scripting or interactively on my shell without thinking too hard about the syntax, but when scripting in bash I require an example or using my snippets to be sure I'm not shooting myself on the foot or writing something that bash will reject right away.

The trick is to use "shellcheck" on your bash scripts, it's an overly anal linter that'll keep you sharp, and it's 2026, everyone can script bash with AI :)

But yeah the syntax with [[, if fi, while stmt; do; done, "$@", case esac, "${!VAR}" and others makes me long for the day fish shell gets "euo pipefail" mode so I can stop writing bash or || true :)

I think the last time that errexit and pipefail were brought up to the fish devs, we were treated instead to an essay about how errexit is a total hack in bash, how it has all kinds of places where it doesn't work as expected, how it's special-cased away for some constructs, etc. None of which is wrong, but it's still a whole lot better than the nothing that we have with fish now.

So we still have this inflection point where scripts eventually have to graduate into a "real" language, and while those languages give us proper data types and structures on one hand, they take away conveniences like pipes with the other. It's 2026, and we managed to crack artificial freakin' intelligence before we got a decently evolved shell into the mainstream. </yells-at-cloud>

Yeap, each time I need a complex shell script, actually Python is a better chose. I just don't need a POSIX compliant shell

     /usr/bin/time -f "%e seconds" fish -i -c exit
     0.21 seconds

Fish gang represent.

I was a bash => zsh/omz person and had these same complaints. But that was 10 years ago. https://github.com/paulirish/dotfiles/blame/main/fish/config...

The baseline fish experience is just better.

Seriously. I do think people should spend enough time with bash or posix sh to be comfortable with it, but I'd recommend everyone at least just try fish. It's a lovely interactive experience out of the box with colors, completions, a great prompt, etc. Plus, the scripting language is quite comfy. Like, somewhere between bash and Python (if you find Python comfy, I guess). At least to me it makes more intuitive sense, once I got over the fact that "it's not bash/zsh."

It's written in Rust, if you care about that sort of thing (I switched before that was a thing). And for simple one-liners, compatibility actually has improved at least a bit (like you can do && now, which wasn't a thing before).

Write your shell-specific helper scripts or personal scripts in fish, write your portable scripts in Python or Bash. Look, I love standards. Sometimes non-standard things make sense though. Sometimes they even make more sense in the right context.

Or maybe you'll hate it. That's fine. People won't know until they try though.

For something newer and even more different, check out nushell. I don't have much experience with it, but a lot of its ideas are enticing.

I've started to play with the idea more recently to try out fish. No appearant reason.. 10 years in zsh is time enough to get comfortable..

Glad to see fish getting some shout outs here. Been using it for over ten years now, and it is super easy to get going on new hosts - it is just one simple install away.

I had the same gripe as the author. OhmyZSH seems too bloated for my needs. Added to that, the defaults adds (and oft unnecessary) emojis to prompts & outputs - something I don't find tasteful or appealing.

I stripped out most of the OhMyZsh functions (which is pretty modular given a shell package) and created a smaller, leaner package (leanZSH) having only the known stuff I may use. I have been using it without much complaints.

https://github.com/gradientwolf/leanzsh

In a similar vein, there is slimzsh [1]. For me, it is a minimal config that enables everything that's useful, and only that. Quite a few others and I have been using this for more than a decade. https://github.com/changs/slimzsh

When I switched to zsh 5 years ago, I went with a stock set up too.

There's quite a few things the OP's post didn't mention about shell history that I think are really important:

    setopt HIST_IGNORE_ALL_DUPS # Never add duplicate entries.
    setopt HIST_IGNORE_SPACE    # Ignore commands that start with a space.
    setopt HIST_REDUCE_BLANKS   # Remove unnecessary blank lines.

It's possible to roll your own prompt that does helpful things without using starship.

Also you can roll your own zsh plugin manager in a few lines of shell scripts, `fast-syntax-highlighting` is a really useful plugin to get real-time feedback when typing commands.

Most of those things are mentioned here https://nickjanetakis.com/blog/i-recently-switched-to-zsh-an..., the post is 5 years old but just about all of that is what I do today still. Since then it has evolved to become better IMO, including using a dedicated Vim zsh plugin which is much improved over the default zsh key binds. Also another plugin to show zsh's tab complete in fzf instead of zsh's window. The tab complete demo video is here https://nickjanetakis.com/blog/hooking-up-fzf-with-zsh-tab-c....

After holding out for literally years after Mac changed their default shell to ZSH, I finally switched over. I didn't love it, but it was okay and had some niceties that I wasn't used to. Then I started to configure it and inevitably ran into Oh My Zsh, and spent some time playing around with that to get it how I liked.

In the end, I realised nothing was as good (to me) as my original Bash set up. I have all the features I need, it's universally supported, and it's fast.

Tip: Install the post GNU2 version from brew

The amount of time this author is complaining about is like, a fraction of the time I spend getting through the first few sips of coffee in my day. I'm sure there's so many bigger time optimizations to tackle first.

This feels like a strange hang up to me.

I notice the delay, but I try to check myself with it. Not everything has to be instant gratification. We're ruining our brains.

This feels like the craziest excuse for slow software.

What workflow involves opening hundreds of shells every day? Like, I've got a half dozen shells open at any given time, and sometimes I gotta refresh or reboot, but even on my worst day in looking at two dozen.

How do you get to hundreds?

Temporary splits to run code close to the editor, tmux popups (they open lazygit or file manager on top of the current tab). Debug runs, where I want to preserve their output for some time, so I keep them in separate tabs.

I use a lot of short-lived terminals. I have zsh+foot configured so that ctrl+shift+n opens a new terminal with the same current directory, so when using Vim, that's as fast as putting Vim in background, but I can tile both windows easily.

I never have more than a one or two dozen terminals at a time, but I definitely open hundred of short-lived ones.

Why? You've said you do but not why you do? Why not leave a terminal open?

Why would I leave it open once I'm done with the task for which I opened the terminal?

They complain about a startup time of 380ms, but with the default configuration it's only 60ms on my laptop. That's faster than the final startup time of 70ms of their custom config, and it has all the features that they added to their config. So with all the features they need OMZ should be fast enough for them? I don't get it.

Startup time depends on hardware and (assume) features you're enabling. Better hardware and less features, less lag.

zsh is still crazy to me. I use bash for everything. I have no idea what I’m missing out on.

FWIW, I still use bash as well. Nothing against zsh per-se, it's just that I know bash, bash works, and there's no particular pain I experience using bash that will obviously be solved by switching. And when you factor in anticipated switching costs, I haven't found any compelling reason to spend any significant time on zsh so far.

Maybe one day though.

I've been using it for the last 6 or 7 years and I can only remember one specific feature I use a lot: "unset HISTFILE" to disable history when I need to run commands with passwords.

Other than that, oh-my-zsh with git, systemd, and fzf plugins. Saves a lot of typing.

The main selling point for me is how easy it is to setup.

Prefixing a space on that command will keep it out of history.

Space before the command will have the same effect

Just out of curiosity, what sort of typing do those plugins save in comparison to doing it in bash? Can you give some examples?

The git and systemd ones create several aliases for frequent commands:

git commit -> gc

git status --short -b -> gsb

git checkout -> gco

systemctl --user restart -> scu-restart

Nothing that you couldn't come up with yourself, but I've been using for so long it has become a standard for me.

The fzf plugin enables a fuzzy finder when you hit ctrl+r or ctrl+t. You need fzf installed.

I remember when I switched to zsh solely for SUNKEYBOARDHACK.

I don't think it is crazy, but I know and love the bash quirks. I've got permanent history setup thanks to Eli Bandersky [1] which I know zsh has a solution to already. But what annoys me with zsh is some of the ways it tab completes when navigating the filesystem, and not by default allowing comments on the command line, e.g. '# github api key blahblahblah', which I can then pull later using phgrep.

Slight pain on a mac to get the latest version and use it as terminal shell, but it gets easier everytime I work on a fresh mac.

[1]: https://eli.thegreenplace.net/2013/06/11/keeping-persistent-...

If you want vi history editing like you are used to in bash for the last 20 years it's subtly different in a manner that makes it insanity inducing. If you use the traditional emacs like editing it's much the same.

Oh that’s good. I’m an emacs guy. I don’t like change.

Yes, I'll throw my hat into this group too. Bash is fine.

YMMV but I have found using zsh too frictitious to be helpful. Sure, theoretically zsh living in a bash world (lets face it, all scripts are bash) is completely fine but reality seems to differ. Copied a one liner from shell history into your script? Crash. Use arrays? Weird bugs. Use shell builtins? Whoa unexpected interactivity!!! Etc...

Bash is absolutely fine as a default shell. As an added benefit, you don't feel like an invalid once logged in to a container or server.

> OMZ adds bloat

They all do... if you want the niceties of not having to write your own shell config, what would you expect?

It's funny how many people pick up OMZ or doom emacs because some YouTuber told them to do it, then drop them in 6 months because they're all bloaty.

I don't think 0.38s is a bad trade-off for convenience when the rest of the tools I need to do my job collectively are another 2s at shell startup. NVM alone adds 0.5-0.6s on my M4 Macbook Air.

Bigger fish to fry if we're being practical.

You can replace nvm with https://mise.jdx.dev/ , it starts effectively instantly and works not only for node versions but all programming languages and tools.

`mise use node@latest`

or asdf

I'm using Asdf too. Have heard well about Mise, but I haven't figured out what the difference is, so I have stayed with Asdf

mise has more features - it is a super set of asdf. For example it can set your env vars when you cd into a directory (like direnv). It also has tasks (which I haven't used) - they appear to be similar to what a Makefile does. So you can potentially replace three tools (asdf, direnv, make) with one.

Thanks! Sounds interesting!

Mise started out using the same plugins as asdf, mostly focused on adding performance and usability improvements. Over time it added more features and security.

Most tools are now directly fetched from github releases without the need for random shell scripts (which is what asdf plugins are).

It also grew to be a task runner and environment manager. At first you might think this is scope creep but they're both opt in and very elegant additions. I don't want to ramble but let's just say they've solved real problems I've had.

I'm a fan of it, and I can't think of a reason why I would use asdf over mise. Its real competition is nix (+devbox/devenv/flox), devcontainers, and pixi.

I will check it out! Thanks for the explanation! Sounds really neat

I am seeing a phenomenon of people wanting to hyper optimise their workflows. It’s nonsensical when you consider the other stuff you need to do or how slow everything else is.

..have you checked. It's 0.04s in my setup. I have it a bit customized but I don't remember chasing milliseconds on config

Holy heck, I just profiled my zsh initialization and nvm was the big source of bloat, holy hell. Similar setup as you (M4 MBP), same amount of startup bloat. Lazy loading it fixes it.

GPT-5.2 changed the nvm initialization script to:

  export NVM_DIR="$HOME/.nvm"
  
  _nvm_lazy_load() {
  unset -f nvm node npm npx _nvm_lazy_load
  [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"
  }
  
  nvm() { _nvm_lazy_load; nvm "$@"; }
  node() { _nvm_lazy_load; command node "$@"; }
  npm() { _nvm_lazy_load; command npm "$@"; }
  npx() { _nvm_lazy_load; command npx "$@"; }

Although this is what Opus recommends, it will give you many issues as you don’t really have any node runtimes in the path (or worse if you do).

What I recommend is replacing it with $PATH=(a command to find the nvm default alias directory, detect the verion and load it from that specific version directory directly) so you always have default node in path and then lazy loading only nvm itself, so you can switch when you need to.

Sorry I don’t have the command handy as I’m on mobile but if you paste the above into Opus you’ll get it.

Thanks. I modified my comment to disclose that gpt 5.2 generated that modification. I'll try your suggestion.

That's why I switched to Mise (https://mise.jdx.dev). Having new terminal sessions taking up hundreds of milliseconds because of nvm isn't the end of the world, but it's annoying when you're in the middle of something.

Mise reads in your .nvmrc files so you don't have to configure anything new.

I never moved to omz (or even zsh; I still rock bash) because I have 10+ years of dotfiles that cover all of my needs. I can see all of the cloud accounts I'm logged into, the status of my Git repositories when I'm cd'ed into them, the number of directories deep my stack is when I use pushd, and have lots and lots of custom functions that save me time. I had moving to zsh in my personal backlog for many years but have yet to come across a pressing reason why I should!

Anyway, yeah, all of this adds startup and command invocation time, but the value far outweighs the latency.

I'm changing to GhosTTY as we speak (from Mac Terminal, because I'm tired of gemini-cli not getting my shift-return for newlines). Wasn't until that process that I learned that new Mac accounts are on a different shell (zsh) than I have (bash). Last time I switched shells was when Apple flipped from tcsh.

Now, I'm deep down the rabbit hole of standardizing all my shells/terminals/configs with Nix. Either a really good or really bad project to start on a Friday night.

It's basically the same, except smarter about command history and auto-completion by default. I'm sure you could get Bash to act the same way with a bit of prodding.

I tries oh my zsh whil switching to it from fish ("the we don't believe in configuration" shell). I thought it would be great with all the popularity it has but 90 percent of the plug-ins are alias definitions which I certainly won't memorize somebody else's. Just found a few plugins I like for the fish functionality I liked. Spent some time configuring it asking for help on the irc channel for zsh when needed. Great people. Zsh is awesome. No plugin manager for me though. Thanks.

Until reading this thread I never knew so many in the industry were against performant software and workflows, but I suppose that explains the state of things.

Oh My Zsh is more sluggish than benching zsh -ic 'exit 0' would suggest. This benchmark will show command lag among other things, which is very noticeable on a slower computer. https://github.com/romkatv/zsh-bench

I use https://github.com/romkatv/zsh4humans. I installed it once, took an hour or two to tweak it to my liking, and haven't touched it since. It's in maintenance mode so I'm not worried about my zshrc breaking randomly. I have transient git prompt, autosuggestions, autocomplete, syntax highlighting, vim mode, a whole bunch of added functions and line editor additions, and my terminal opens in one frame. It feels more like an extension of my mind than a tool I'm interacting with. OMZ by comparison, feels like typing over a slow ssh connection.

This is the .zshrc file I have in my dotfiles.

It auto installs everything if you don't have it. Starts effectively instantly.

Right. A lot of people when they say "minimal" mean "simple looking at first glance", and it rarely is.

Super easy to setup, and works very well

Like many I installed omz and ran it as the default for a long time. After a while I looked to optimize my shell starts and realized I was only using a fraction of the functionality.

So I figured out what I was using and created my own very paired down version of what I needed. My boot times are much faster and I’ve been totally happy with it. I also learned a lot more about shell configs as a result.

In case the authors sees that, your default shell is configured via [0]:

   users.users.yourUser.shell = pkgs.fish;

[0]: https://search.nixos.org/options?channel=unstable&show=users...

I have been using omz for YEARS. I have practically grown up with it. I resent that I would have never noticed that it took several hundred milliseconds to load, if it were not for this discussion. I never felt the delay particularly unless I was in a very large Git repository — which is rare. On the bright side, now I know about `fish` and am learning there are some nice features I never had in ZSH (i.e. much more advanced autosuggest.) What I basically use omz for is 1) autocomplete, 2) git aliases, and 3) my beloved prompt. In about 30 minutes, Claude helped me port my prompt from ZSH, autocomplete comes OOB, and a cursory Google search shows someone has made a Fish plugin to satiate my Git alias muscle memory. I could leave Zsh/omz in the rear view mirror tomorrow — but for why? I never would have noticed before this discussion...

I may not need this sort of shell bling. And I don't use it. But my first Unix system was an early version of Xenix, which had the original Bourne shell that didn't even support cursor up to get a previous command. (I do use cursor up, C-r, and the shell editing commands.)

But yesterday's conveniences become today's essentials, and those who came in after me have their expectations set by the much more sophisticated things available at the time. Like, I'm still flabbergasted by people—working professionals—who go "I can't program without syntax highlighting, autocomplete, and my IDE generally going bing bing wahoo at me as I work, and I don't know how anybody can." We just type the code in. Like we all had to back in the day.

Anyway I can certainly see where someone younger than about 35, or who came to Linux late, would be completely at sixes and sevens without their colorized racing-stripes shell prompt.

“Still gangsta” I mutter to myself as I syntax-highlight punchcard #818 by hand and Port-a-Punch a replacement.

My zsh config has three things:

    setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
    bindkey "^R" history-incremental-search-backward
    autoload -Uz compinit && compinit

The first one is mentioned in `git-prompt.sh` that comes with git, which needs to be sourced as well.

Surprised no one has shout out zsh4humans, perhaps because it's basically in maintenance mode but it's not like I need any new features. Love the ssh teleport feature.

https://github.com/romkatv/zsh4humans

Are we really quibbling over 400ms startup delay to open a new terminal?

Of course. We're nerds. You should have seen the passionate discourse, a couple days ago, for Brave browser saving 45MB of memory!

Yes! The very famous xz hack was only found, because a German wondered why his ssh session lagged 200 ms at the start. Everyone should go mad when their main tool lags a few hundred milliseconds. It is unacceptable that we sit on machines, that run billions of calculations per second and our software still lags.

400ms here, 400ms there, and before you know it, you're dead. I've switched terminal emulator and upgraded computers for less.

Yes, and hundreds of developers just spent 5 minutes reading about it.

This investment makes sense for OP who opens hundreds of terminal sessions, but does it make sense to bother about 1s delay when they start the terminal session once in a while? I have several sessions opened all the time, the last time I wasted my 1s on zsh was in 2025 when I rebooted my machine due to a nvidia drivers update.

400ms is a ton if you have a terminal centric workflow with short lived shells.

HN has gone on a decade long crusade against Electron, of course 400ms is a lot.

I used Oh My Zsh for years, but there were literally 3-4 features I relied on: autocompletion, git plugin, history search, and one theme.

For some reason it was slow to load which I found annoying, so I used Claude Code to optimize it. In the end I ended up removing Oh My ZSH entirely, now I have a single .zshrc file that contains everything, and it became much faster.

Similarly I moved from Packer to Lazy.nvim and updated a number of libraries, and from iTerm to Ghostty, Claude Code essentially converted my configs in a matter of minutes

> My workflows involve opening and closing up to hundreds of terminal or tmux tabs a day. I do everything from the terminal. Just imagine that opening a new tab in a text editor would take half a second every time.

This sounds like overoptimization on a neglible time loss for what is essentially an unique (and dare I say: broken?) workflow.

I use terminals a lot ... but I work with 4-5 day-persistent terminals that I open once a day and keep in the background. The QoL effects of omz outweigh microtuning startup times significantly.

I'm incredibly impatient with my tools and I've been running omz for many years. I spend my days in tmux/vim and generally run 6-12 shells at a time.

Some quick troubleshooting many years ago narrowed the vast majority of the problem down to the git plugin, especially for large, old repos.

I disabled the git plugin and everything has been fine ever since.

Figured I'd dig deeper and bring back the current branch name without the bloat at some point, but it hasn't bothered me enough to do it.

Current branch without bloat is to cat .git/HEAD, and if that didn't exist, run git symbolic-ref HEAD. The first is faster and works in the common case where you're in the top of a git repo. In either case, run it through ${branch##*/} to strip down to just the current branch.

I have used this for a long time, never understood how people would put all of git in between them and the next prompt.

I've been an oh-my-zsh user for many years now, being very happy with the very small set of features I use from it. Previously I could never think of trying to figure out how to replicate the features I need without the other features from oh-my-zsh, which does make the shell noticeably slower.

Just now, after reading this article, I used Claude code and have removed the OMZ config within 5 minutes. Here's my prompt - maybe others could find it useful. I ran this from `~/.oh-my-zsh`.

``` Here's my zsh config - I'd like to remove oh-my-zsh and replace the provided functionality with just raw zsh. i use starship for my prompt so i don't need any help there.

  can you explore the oh-my-zsh codebae and see what it would take to replicate the features it currently provides me in the shell?

  my zsh config below:

  export ZSH="$HOME/.oh-my-zsh"
  ZSH_THEME=""
  DISABLE_AUTO_TITLE="true"
  plugins=(direnv fzf)
  source $ZSH/oh-my-zsh.sh

--- CLAUDE RESPONSE --- Minimal Raw Zsh Replacement

  Since you use starship and have DISABLE_AUTO_TITLE=true, you can skip prompt and title-related code. Here's what you'd need:

  # Completions
  autoload -Uz compinit
  compinit

  zstyle ':completion:*' menu select
  zstyle ':completion:*' matcher-list 'm:{a-zA-Z}={A-Za-z}'  # case insensitive

  # History
  HISTFILE=~/.zsh_history
  HISTSIZE=50000
  SAVEHIST=10000
  setopt extended_history hist_expire_dups_first hist_ignore_dups
  setopt hist_ignore_space hist_verify share_history

  # Directory navigation
  setopt auto_cd auto_pushd pushd_ignore_dups pushdminus

  # Key bindings (emacs mode)
  bindkey -e
  bindkey '^[[H' beginning-of-line      # Home
  bindkey '^[[F' end-of-line            # End
  bindkey '^[[1;5C' forward-word        # Ctrl-Right
  bindkey '^[[1;5D' backward-word       # Ctrl-Left
  bindkey '^[[3~' delete-char           # Delete

  # Colors
  autoload -Uz colors && colors
  export CLICOLOR=1  # macOS ls colors

  # Plugins replacement
  eval "$(direnv hook zsh)"
  eval "$(fzf --zsh)"

```

Granted I've only done this like 5 minutes ago and might be missing functionality I'll realise later, but a quick few checks give me hope I have all the functionality I want.

I have given up on any external bash configurator a long time ago, instead I write my own bash prompts these days, they lack a lot of functionalities but I am much happy with them for now, also a shameless plug: https://martianlantern.github.io/2025/11/updating-my-bash-pr...

I use a subset of omz by cloning it and manually sourcing the plugins I want myself rather than initializing the entire omz system. No themes, no checking for updates, etc. For me, it’s the best of both worlds.

I describe my setup and how to use it on a fresh MacBook here: https://github.com/agrounds/dotfiles

I have these plugins: git, zsh-autosuggestions

    /usr/bin/time -f "%e seconds" zsh -i -c exit
    0.06 seconds

This is acceptable, maybe the zsh-autocomplete is the problem for author or something else?

I originally switched to ZSH + Oh My Shell because it opens so fast. Ideally plugins would initialize asynchronously but it's not very easy with shell scripts I think.

FWIW, that’s not a great way to benchmark zsh.

Check out zsh-bench⁽¹⁾ for a more authoritative approach, including first prompt lag, first command lag, input lag and exit lag.

⁽¹⁾ https://github.com/romkatv/zsh-bench

I have been using OMZ for the last 8 years but recently made the switch to plain zsh with : - starship for a better prompt - Claude ported plugins I was using from omz (extract, sudo) - custom written aliases that were muscle memory - zoxide for the a command

So far that has been a great move, my terminal tab feel snappy again. One thing I miss (but I’m sure I could find a way to replace it) is `cd ….´

This is not an issue for me due to my workflow.

I have a script for each of my projects that I run when I open a new terminal window (Alacritty). The scripts set up tmux with 3-8 terminals, each terminal launches a components, utility or just sits in a folder from which I later run commands.

Having said that, I use only a few zsh plugins, and have a theme configured to not run commands that add extra latency.

I use OMZ because it lets me rely on popular defaults instead of bike shedding and rolling my own. Its main advantage is convention over configuration. For instance, I just have to learn the git plugin aliases once, and then I can use them anywhere with OMZ + git plugin. Is there any lighter alternative that is compatible with OMZ plugins?

FWIW, we have tracing functionality to help you identify why your local environment/config is slower than you'd like.

https://github.com/ohmyzsh/trace.ohmyz.sh

I concur. I tried oh my zsh and for a while I thought I was doing something wrong. My experience was terrible. But it turns out that many people did not mind the bloat and the prompt lag. It was not for me. I uninstalled it and I have such a bad taste in my mouth that I am very reluctant to try any of the alternatives.

I agree, I used omz a while now but I have since also realised that the features I uses are so basic, it really does not warrant a whole software project as a dependency.

So I went and had Gemini make me a zsh config with the features I actually use. Took 15 minutes to get all the autocompelte, aliases and search functionality and done.

> Once in a while, it also checks for updates, which can take up to a few seconds when you open a new tab.

This can be disabled fairly trivially. I then alias the update command to a homebrew update alias.

https://stackoverflow.com/a/25876379

The problem with zsh, as with a lot of open source tools is bad defaults. If only zsh had a better out of the box experience then OMZ wouldn't be needed. I used maintain a lot of configs, over 10 years I just keep forgetting what did I set up. I don't want to be bothered with this anymore.

Prezto is faster than OMZ, and has been for over a decade. Starship is faster still. I switched from using Prezto standalone to using Prezto + Starship and relying primarily on Starship several years ago. I'd be surprised if many people are still using Oh My ZSH in 2026 vs using Prezto, anyway.

zsh4humans is even faster than Prezto, according to their benchmarks. that’s what I’m using daily.

Didn't know about starship and need to check it out.

Shameless plug: I wrote a detailed git prompt in C which is similar to posh-git on Powershell: https://github.com/mahesh-hegde/promptsynth

Oh My Zsh adds bloat but sets sensible default settings compared to vanilla zsh. I tried using zsh without OMZ and I realized how many things are in OMZ which I took for granted, especially keybindings.

~150ms with minimal setup is good enough for me, although I would prefer <50ms.

Well yeah, you need antibody https://getantibody.github.io/ and then whatever plugins you desire. Been using it for years and it's never been anything other than fast and reliable.

Why antibody and not any of the 60 alternatives? Is it truly the best among them or is your choice sub-optimal?

Thinking about that I realized I prefer not to use any plugin manager at all.

I mean it's not like I've done any formal benchmarks but like I've used a bunch of plug-in managers and antidote, sorry antibody is the old one, it's just so much faster than all the others.

github says in maintenance since 2022 and that users should move to next great thing, antidote

Oh shit you're right it is actually antidote, God why do they have to name them the same things. Even their websites are similar.

Like others I don't use too many of the features but Oh-My-Zsh is so easy to install.

Even better recently I discovered that FreeBSD has a package for it!

`pkg install ohmyzsh` and 5 seconds later it's ready. Plus I figure it's a bit more secure and insulated to any ohmyzsh breaches.

It's funny how there are operations so sensitive to latency that even half a second feels too long.

However I agree with other comments that the author's baseline of 380ms is suspicious. I get 150ms (full config, 6 plugins) vs 50ms with no config and plugins.

Had this problem awhile ago of my zsh startup being slow. Just opened claude code and told it to benchmark my shell start and then optimize it. Took like 5 minutes and now it's ultra fast. Hardly any idea what it did exactly but worked great.

Agree. If you want some colors, git status, a few convenience functions and a clean prompt, this is my current setup: https://monokai.pro/zsh

At some point you need to remove the training wheels, otherwise you'll never learn to ride the bike.

At first, you need them. You'll fall without it. But if you still rely on them after a while, it's not a good sign.

I switched to Prezto because of how slow OMZ is, been really happy with it. At one point it started causing issues with the IntelliJ environment reader but it’s been perfect once I sorted that out.

I have not a small number of plugins on fish and I've never noticed a problem with startup time. I do wish there was a better way of managing or installing plugins. It just feels so fragile.

I had my phase of having a fancy shell with all bells and whistles. I’ve now settled with the default terminal so that 1. It is fast, 2. Whereever I work, I have the same experience.

These projects tend to go a certain direction...

After a few months with lazyvim I'm missing barebones nvim. Batteries included is nice but requires maniacal restraint.

I have a fast machine, never noticed a difference in shell start up time between with and without and given how much more pleasant it is with I'll take the hit.

I'll go a step further, you probably don't need zsh at all. Once you install Starship there's not much difference if you just use bash.

I've discovered plugins zsh-autosuggestions and fzf (available out of the box) and OH MY ZSH am I impressed with my quality of life improvement.

I don't use it because I'm tired of having one package manager per tool you want to use. I can handle a simpler shell configuration.

huh, is this a problem people really have? I just have a plugin that lets me type before zsh loads and I don't really have a problem with this, even before that i didn't really notice a problem since my 'default' configuration is .12s.

   time zsh -i -c exit
  zsh -i -c exit  0.12s user 0.09s system 81% cpu 0.276 total
  ~

What plugin?

  # Enable Powerlevel10k instant prompt. Should stay close to the top of ~/.zshrc.
  # Initialization code that may require console input (password prompts, [y/n]
  # confirmations, etc.) must go above this block; everything else may go below.
  if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
    source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
  fi

Too many shells.. I got so much hard earned knoledhe on taming bash I just can’t see a reason to switch.

I am just glad that it is sub-second start time, where with powershell, it was upwards of multiple seconds

I agree. And you probably neither need Omarchy, CachyOS, etc. Choose boring and get peace of mind.

CachyOS is basically arch on easy mode. I used to spend countless hours tinkering with arch but then I got older and don’t have much time. Plus there are helpful meta packages for gaming that work great out of the box, which for a gamer like me sans Windows is pretty awesome.

I've tinkered at most an hour on my arch install and it's just been running smoothly. The installer these days is easy to go through as well. It's the same for bash, very little customization, then it runs smoothly for years.

I'm not saying CachyOS is bad, just that it is in my opinion another layer of complexity that may change/deprecate/etc.

That’s fair, the more steps you take away from the source distribution, the more variances become a potential for trouble. Also it’s been over a decade since I used arch, it’s probably a whole lot better now.

>I used to spend countless hours tinkering with arch but then I got older and don’t have much time.

Have your lost your old configs that you worked hard on? That's a shame if so. I love moving my configs I've worked hard on to new machines and instantly getting up and running in a now-familiar environment. It saves so much time and effort.

> Have your lost your old configs that you worked hard on?

I mean… it was so long ago. Actually it’s more than 15 years ago, on used hardware no less. Needless to say, I don’t even have remotely the same hardware anymore - I’m on AM5 / DDR5 right now.

The tips in the article on enabling vi mode and fzf keybind are worth the read imho

I was annoyed by this enough that I ended up cloning the OMZ repository locally, and stripping out all the modules I don’t use. And now I just have it as part of my dotfiles[1].

It's just a handful of files and I manually source them in my zshrc[2]:

    source $ZSH/lib/async_prompt.zsh
    source $ZSH/lib/key-bindings.zsh
    source $ZSH/lib/completion.zsh
    source $ZSH/lib/history.zsh
    source $ZSH/lib/git.zsh
    source $ZSH/lib/theme-and-appearance.zsh

It's essentially the same as omz setup I was using before, but loads in just ~25ms (Note: it's on a hard drive, with ddr3 ram and 18ms out of that is spent by compinit)

It also fixed another issue I had with Oh-My-Zsh: whenever they (very rarely) tweak their default config - it breaks my muscle memory.

For me the bloat is acceptable since it saves so much time and JustWorks (Tm)

This thread feels so foreign to me. I use basic ass vanilla Windows terminal. It’s fine. I also use the vanilla built-in to VSCode terminal. It is also fine.

Terminals are such a small, unimportant part of my job I barely even think about them.

Conversely, I spend about 60% of my working day in the terminal, with another 20% in Zed. Wild how much workflows differ, isn’t it?

Yes, Windows users don't have time for such luxuries when they're constantly fighting a losing fight with an increasingly hostile OS. Playing whack-a-mole dismissing ads, dismissing Edge and reopening links in your preferred browser, waiting for React to render in the start menu, coping with the ever increasing theft of personal data, and on and on and on the list goes. The rest of the time is spent on working around Windows oddities that other developers using sensible OSes simply don't need to deal with. No wonder there's no time to think about anything else.

I also use Linux and Mac. And sometimes a little bit of Android.

Win11 Pro is also fine. I spend radically less time fighting Windows than I spend fighting Linux userspace disfunction.

Shaving milliseconds off of terminal load time seems like a silly thing to optimize for. I notice omz takes a brief moment but it’s never bothered me.

Switching from OMZ shaves a few ms on my very fast desktop machine. It shaves seconds of SSHing into a heavily loaded server.

> affects shell startup time

You'll never get back those milliseconds. Just like I can't get back the time I wasted reading this article.

    /usr/bin/time -f "%e seconds" zsh -i -c exit
    0.04 seconds

I think they are just doing something wrong. Why people are upvoting this nonsense

Am I the only one that uses ohmyposh with fish? I have a killer custom posh theme that I’ve been using for years and the performance is fantastic.

Slightly off topic but:

>> My workflows involve opening and closing up to hundreds of terminal or tmux tabs a day.

What?!?

Should have been titled "I probably don't need Oh My Zsh because of my weird niche tab workflow" but that's a lot less clickbaity.

I use fish now instead, honestly a nicer shell and shell language all around.

You probably don't need zsh. POSIX shells are holding us back.

Show me an environment where I can interact with my system programmatically, where I can compose together arbitrary tools, and which will never, ever, ever break on me, and I'll switch! My experience with graphical environments has been that they rarely compose, often break, and constantly make arbitrary changes that break my workflow. So every time I try something else I end up coming back to the terminal.

But I agree that terminal environments have serious shortcomings. I think it's a real shame we haven't created anything else that does what the terminal does, and I think it's mostly for lack of trying.

Nushell. Still a terminal experience. But not a POSIX one. https://www.nushell.sh/

Colorful outputs and elaborately decorated error messages are cool but maybe it shouldn't deviate that far from POSIX shells.

    $ trap '' chld
    $ nu -c test
    Error: nu::shell::io::uncategorized_error
    
      × I/O error
      ╰─▶   × failed to get exit code
    
       ╭─[source:1:1]
     1 │ test
       · ──┬─
       ·   ╰── Uncategorized error
       ╰────
    
    $

There are other options if you want POSIX. But nushell just does things differently (and in a much more sane way with pipes).

Why would you want `test -e "$foo"` when you have `$foo | path exists`? Why `test -n "$foo"` when you have an actual == comparison and pattern matching expressions? And you don't have to worry about quoting things just right in any of the situations.

Yes, you need to learn a little bit of a new thing. You can even implement a test function itself if you really want to. But sometimes it's nice to just dump the legacy baggage.

https://fishshell.com/ https://xon.sh/ https://www.nushell.sh/ https://elv.sh/

You're replying to someone that says POSIX shells are holding people back, not that the terminal is a bad idea, there are many alternative shells which offer benefits over POSIX shells. fish-shell has everything you want from an interactive shell included, xonsh is a mix Python shell, nushell and elvish are adding types and other things to shell.

The VT protocols that all shells have to confirm with are pretty dated and I'd love to throw them off the roof for something less stateful and with multiple font sizes but there's no arguing that text based interfaces are good.

I'm a nushell user but like... job control in nushell is pretty miserable still unfortunately.

Nushell is definitely my fav of the set (xonsh is a neat experiment but ultimately is missing pipeline programming that nushell gives....), and I write personal shell scripts for myself mostly in nu.

Aside: for shell scripts, my preference is something like nu, then python + stdlib, giving me argparser etc, then just zsh/bash/whatever. Seriously annoying how POSIX shells do not give good argument parsing, tho I get it's a hard problem

zsh isn't strictly POSIX compliant either but this is fair and I should've read that comment a bit deeper.

Now I'm tempted to try xonsh. It looks like it support the amount of bash that I know, and everything else I can just do in Python. (TBH, the things that I would need Python for are obscure enough in bash that I wouldn't otherwise write them myself.)

> I think it's a real shame we haven't created anything else that does what the terminal does, and I think it's mostly for lack of trying

I'd rather just take terminals a step forward, which I agree hasn't happened due to a lack of trying. But the people who aren't trying are the people who are instead tricking out zsh with plugins. I'm a nushell fan myself but my point here is not

> try nushell

but rather,

> be willing to try things that aren't backwards compatible with `sh`

If more people relaxed on that sticking point, we could actually benefit from the excellent post-POSIX work that has been done. As it is, people are reluctant to try new shells for some reason.
