alt Hacker NewsTangentially related. Don't ever put "." in your PATH. I used to do this to avoid typing the "./" to execute something in my current directory. BAD IDEA. It can turn a typo into a fork bomb. I took down a production server trying to save typing two characters.

I like to follow my own convention where I name files with shell scripts with an extension: .sh for POSIX-compatible scripts, .bash for scripts with bashisms or .zsh for scripts with zshisms.
If I ever wanted to achieve what you initially wanted to achieve - I could use something like
alias -s sh=sh
alias -s bash=bash
alias -s zsh=zsh
Just like I do bind .txt and .conf to 'less', .pdf to 'qpdf', .json to 'ijq', video formats to 'mpv' and so on.
Might I ask exactly what the typo was?
Elaborate?? "." has been at the end of my PATH for like 20 years.
lol. What a beautiful footgun — for such a tiny optimization.
It used to be very common to "own" a unix system by adding a `ls` binary in some folder and waiting for an administrator to run it.
