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
Sure, things usually put env in /usr/bin, but there’s no guarantee for that. All standards like POSIX guarantee is that the standard PATH contains certain binaries.
Hardcoding /usr/bin/env is probably your best bet, but hardcoding any path is making assumptions that POSIX complaint shells don’t guarantee.
That’s why
#!envis probably your best bet, but people hate shebangs without absolute paths.
