Ask HN: What are some small scripts you use daily?

    TODAY_DIR="$HOME/today/"
    DATE_DIR=$(date +'%Y-%m-%d')
    
    if [ ! -d  $TODAY_DIR$DATE_DIR ];
    then
        mkdir -p $TODAY_DIR$DATE_DIR
    fi;
    
    echo $TODAY_DIR$DATE_DIR

    cp somefile.csv $(today)

alias whitenoise='play -q -c 2 -n synth brownnoise band -n 1600 1500 tremolo .1 30'

It plays some fuzzy whitenoise, which drowns them out and lets me keep focused (music is often distracting to me).

eg: make deploy; blingle

#!/bin/bash

MSG=${@:-"Job complete"}

notify-send "$MSG"

curl -s \

  --form-string "token=TOKEN" \

  --form-string "user=UID" \

  --form-string "message=$MSG" \

  https://api.pushover.net/1/messages.json

In each of those scripts, I typically have a one liner depending on what the project requires. A simple build one is:

    #!/usr/bin/env bash

    make build

    #!/usr/bin/env bash

    docker run foo/bar

    #!/usr/bin/env bash

    python manage.py runserver

Then I add each script to my .git/info/exclude for each project. It saves so much time switching between projects to not have to remember any particular one's build or run commands.

I use it all the time when I have some UNIX pipe emitting things and I want to "see" the uniques before I do sort | uniq -c type things.

#!/bin/sh awk '{ if (!h[$0]) { print $0; h[$0]=1 } }'

push -> git push origin develop; git push origin master; git push origin --tags; terminal-notifier -title "Pushed to Git" -message "Project X"

In another directory, push may push different branches. Ditto for pull, release, keep, etc

Use them daily.

e.g.

  To connect: anyconnector -c env-name
  Disconnect: anyconnector -d
  Get status: anyconnector -s

I use the following script to switch to dual external monitors at a standard resolution, and a counterpart script to switch back to the internal hidef monitor.

If only I could reliably fix xfce4's panel placement all of the time...and not have to restart chrome and pycharm/intelliJ on each display change!

  #!/bin/bash
  
  EXT1=`xrandr --current | sed 's/^\(.*\) connected.*$/\1/p;d' | grep -v ^eDP | head -n 1`
  EXT2=`xrandr --current | sed 's/^\(.*\) connected.*$/\1/p;d' | grep HDMI | head -n 1`
  INT=`xrandr --current | sed 's/^\(.*\) connected.*$/\1/p;d' | grep -v ^DP | head -n 1`
  
  
  xfconf-query -c xsettings -p /Xft/DPI -s 96
  xfconf-query -c xfce4-panel -p /panels/panel-1/size -s 28
  
  xrandr \
  --output VIRTUAL1 --off \
  --output ${INT} --off \
  --output ${EXT2} --mode 1680x1050 --pos 0x150 --rotate normal \
  --output ${EXT1} --mode 1920x1200 --pos 1680x0 --rotate normal --primary

    cd()
    {
      command cd "$@"
      [[ "$OLDPWD" == "$HOME"/Work/* && ! -z "$VIRTUAL_ENV" && "$OLDPWD" == *"${VIRTUAL_ENV##*/}"* && "$PWD" != *"${VIRTUAL_ENV##*/}"* ]] && deactivate
      [[ -z "$VIRTUAL_ENV" && "$PWD" == "$HOME"/Work/* ]] && next="$(sed -e "s/^.*Work\///" -e "s/\/.*$//" <<< "$PWD")" && [[ -d "$WORKON_HOME"/"$next" ]] && workon "$next" && unset next
    }

rsync -rlptvDC --progress --rsh="ssh -l username" * myserver.com

That seems to be somewhat popular on github, but I rarely receive feedback so I'm not sure if people star because they use them too, or just because they suspect they might.

    $ cat `which did`
    grep $1 ~/.bash_history | sort | uniq

I don't mind having a large history file laying around because it's so useful.

  rebase-all () 
  { 
      old=`git rev-parse --abbrev-ref HEAD`;
      stashed=`git stash`;
      for b in $(git branch --format '%(authorname) %(refname:short)' | sed -ne "s/^`git config --get user.name` //p" | grep -- -);
      do
          git checkout $b && git rebase origin/develop && git push --force || ( git rebase --abort && echo Could not rebase $b );
          echo;
      done;
      git checkout $old;
      if [ "$stashed" != "No local changes to save" ]; then
          git stash pop;
      fi
  }

I wipe the inbox for my test gmail account every hour at the :45 minute mark using a ruby script. I don't automate the sending because it's part of the education of the prospect.

Biggest timesaver in the world for someone who listens to as much music as I do and doesn't want to deal with manually transcoding FLAC files.

iTunes and Apple Music will soon support FLAC natively, though -- previously it was out of necessity, space, and not wanting to use VLC and lose my main/single use of my Apple Watch. It's still about the latter two.

I recently also set it to output a manifest that I can feed into rsync on my work computer to pull my library from my backup server.

by default it shows a list of topics. Then if you run it with the topic, it displays the details about the topic. I use it to remember how to do less frequent stuff at my day job.

    # Helper function for running command in each subdirectory under current one.
    function each {
      if [ -z $1 ]; then
        : # If no command is given, then this is a no-op.
      else
        find . -maxdepth 1 -mindepth 1 -not -path '*/\.*' -type d -exec sh -c "(echo {} && cd {} && $* && echo)" \;
      fi
    }

    # Helper function for navigating tmux sessions
    export WORKSPACE_ROOT=$HOME/workspace
    ws() {
      if [ -z $1 ]; then
        if [ -z $TMUX ]; then
          tmux attach-session
        else
          cd $WORKSPACE_ROOT
        fi
      elif [[ $1 == 'ls' ]]; then
        tmux list-sessions
      else
        tmux attach -t $1 || cd $WORKSPACE_ROOT/$1/src; tmux new-session -s $1
      fi
    }

    # Helper function for running command in each subdirectory under current one.
    each() {
      if [ -z $1 ]; then
        # If no command is given, just exit
      else
        find . -maxdepth 1 -mindepth 1 -not -path '*/\.*' -type d -exec sh -c "(echo {} && cd {} && $* && echo)" \;
      fi
    }

Makes deployments blistering fast now that I've got 30 Megabit/sec up though... :)

ahk scripts:

- Easy Window Dragging (KDE style)

- Rocker (click left-right mouse button to go forward in explorer etc, right-left to go back)

- hidedesk (hides desktop icons unless I click on the desktop, sadly a bit buggy)

- some custom script to unify hotkeys for the brightness of my external dell monitor and my laptop screen.

browser fixes:

- some drag to scroll js for greasmonkey

- shortcut for bookmarking to pocket with keyboard only (with tags)

It’s transformed the office. It’s the little things ya know.

`watch-copy [copy to dir]`, which watches for changes in the current directory and builds and copies to another directory.

`set-lights [group name] [on/off/high/low]`, which posts commands to a Hue bridge.

Also use it a lot for syncing dotfiles in my user directory between my work and home computers.

The most common one I use all the time is one that changes the command prompt to show what git branch I'm on when in that directory. Just google it if you'd like.

If you repeat some command a lot or a chain of commands and it takes a lot of tedious typing, then script it.

    web [master=] $ cat $(type -P shipit)
    #!/bin/bash
    exec ./shipit
    web [master=] $

    #!/usr/bin/env python
    import sys

    def unescape(string):
        print eval(string)

    if __name__ == '__main__':
        unescape(sys.stdin.read())

Plus all the scratch dirs are in one place so cleanup is a breeze to free up space.

#!/bin/bash

for i in /sites/*/.git; do ( echo $i; cd $i/..; git pull; ); done

   #!/bin/bash                                                                       
   xrandr --output DVI-I-1 --brightness $1                                      
   xrandr --output HDMI-0 --brightness $1  
   xrandr --output DVI-D-0 --brightness $1
