I thought you weren't supposed to use Fish as your login shell directly since it isn't fully POSIX compatible

Why would your login shell need to be fully POSIX compatible?

[–] LiveLM@lemmy.zip 1 points 1 day ago

They warn about it on their home page, so I assumed using it could bust your system. My bad.
I think they also had harsher wording about this in the past but I might be misremembering...

This was more of a problem when they didn't support basic POSIX-isms so even basic calls to sh like sh -c 'echo "foo" && echo "bar"' would fail. Less of a problem now but you never know when a random script is going to rely on some obscure POSIX flag

Scripts who use #!/bin/sh are independent of your login shell.

What does any of that have to do with your login shell?
