That's why I included Perl, it is always there. Just don't code as if you were in the nineties and Perl is a perfectly legitimate language, even more so for shell tasks. Bad and good doesn't depend so much on the language but the coder.

Why not use Perl or python for scripting tasks? Bash script is terrible imo.

Fzf doesn't need fish, though. I use it with bash.

If you learned that today, you must have been living under a very cosy rock of blissful ignorance. This scheme is still in use even now in a wide array of poorer countries.
