Command Line One-Liners

It's unfortunate the #2 listing is outdated (python2 vs python3)

1. What's up with that? Looks like testing bots, because most of the messages don't make sense at all.

2. They should mitigate these bots, because ultimately it will make the website annoying to visit.

Completely agree, the spam is a turn off for the site. I assume if someone is smart enough to build a site like this, they know how to eliminate the spam but are just lazy.

The word "Fu" (pronounced "foo") is a reference to "Kung Fu," a Chinese martial art. It is used colloquially in combination with other words to mean "something someone has to practice to become a skilled expert in." You might see "Google-fu," as in, "skill using search engines to find what you're looking for," or "Spreadsheet-fu," as in, "skill using Microsoft Excel or other spreadsheet programs," or similar things.

In this case, "Command Line Fu" is meant to suggest that the command line is something you can practice to improve your skills with, analogous to a martial art. It's not meant to be pronounced "F you"—though I'm sure you're allowed to continue doing that if you find it amusing!

I think it would only makes sense if the target system on which the script may run has `zip` but not a version of `tar` supporting the `-z` option. That's certainly unlikely to ever happen.

There's also `tar -cvf - | zip blah.zip -` with the idea that it's a poor man's way to parallelize the `tar` and `zip` processes but I don't think it makes a real difference in recent implementations of `tar`. At least in a couple of tests I've just run, it's just as fast.

Found some powershell too, but curiously, they seem to be all mixed together.

No, most of them work fine in vanilla sh too :-)

Where do you think ChatGPT gets the data to try on to produce results from a query? I suspect websites like this are part and parcel of the training data it scours the open web for.
