Hi all I have a quick question. Is it better for my zsh shell to be in /usr/bin/zsh or /bin/zsh. I remember reading that one of them would mess up the whole system since zsh is not posix compliant. I believe that szh shouldn’t be set as the root shell. I now have it in /usr/bin/zsh, is that good? So now when I drop into a root shell I don’t get they autocompletion feature that zsh has. I’d also lose that fancy theme. Does that mean my root shell is still bash? Thanks
On your system. Check out the table halfway down where env is located on different systems: https://www.cyberciti.biz/tips/finding-bash-perl-python-portably-using-env.html

There is even less guarantee for it to be anywhere else.
Because it is the convention.
It definitely isn’t. That might work in your user space instance of bash in the desktop, but will likely fail in a script invoked during boot, and is guaranteed to fail on several non-gnu/non-linux systems.
#!/usr/bin/envis the agreed convention and there is no probably or but about that. If that does not work on a system it is a bug (looking at you BusyBox containers 🤨).
