please dont use chsh
doesnt mean your whole OS needs a different shell
chsh just changes the shell when you log in to a shell. all the other shells are still available and usable. any script starting tieh #!/bin/bash
will still run with bash, even if you're using zsh or fish.
Yes bash scripts still work, but I heard there may be other things that randomly break.
Many things use #!/bin/sh
for example, which often is a link to bash, but may not work anymore.
chsh does not modify /bin/sh
Maybe you're thinking of a certain video from a certain YouTuber who linked /bin/sh to fish?
Haha no didnt think of that? Hm, I dont know why it would be an issue then. POSIX compliant shells should be no problem, but I wouldnt do it for fish
It will never matter what your login shell, unless you have bash specific scripts in your login. chsh -s /bin/fish $(whoami)
is fine.
