So I’ve been using Linux now for a while, and am looking to migrate my dev environment to vim and spend more time in the command line. I’m fairly comfortable with bash but by no means an expert. I’ve used zsh with some minor customization but just recently learned about fish. I’d love to hear people’s opinions.
I use fish because I have better things to do than tweak my shell configuration and debug shell plugins.
When I tried oh-my-zsh and prezto (I think?) they came with tons of plugins that performed badly and made it hard to get things done (specifically, they ran git status synchronously on every new prompt, which does not work well in a moderately large repo). Fish had similar features but wasn’t horribly slow, so I use it.
When you’re working on a remote server you’re probably not going to have fish available.
I use Fish shell and while it is pretty nice on its own, the fact that it is non-standard does cause problems. Many times you will search for something online and you’ll find nice bash results, which either you will have to execute directly in bash or modify to work correctly in Fish.
I don’t think all of Fish’s design choices are the best, either. But for an OOTB experience, it is nicer than either Bash or Zsh.
Let the religious shell wars begin … again
Only right answer is of course TCSH. Not much documentation and support, ancient but still receives new bugs in 2021 (on Debian), but attackers hate it! (I love it)
My real suggestion is to learn zsh and fish (and bash). Try using them for all your purposes and in the end you will automatically find the one (or more of them) that suits you best and that you like most for your daily tasks.
I like zsh with oh-my-zsh and Powerlevel10k. This gives me a clear indication of which system I am on and remains POSIX-compliant.
The biggest deal breaker for me for shells like fish are the they are not POSIX-compliant and I need to use remote systems regularly. Doesn’t make sense to use something with a different syntax to me.
