Hi. So I’ve been a fish user for a while, but I’ve always gotten frustrated with it not being POSIX compliant. I tried to use zsh with oh-my-zsh to still benefit from fish’s capabilities on zsh, but I had 2 problems with it: it was incredibly slow, and it wasn’t as good. As I recently found out, the plugins can just be sourced in zsh directly, skipping oh-my-zsh, and fixing my speed issues. But the second issue remained: zsh-autosuggestions is just not as good as fish’s autocompletion feature, which suggests commands in a user’s PATH, as well as autocompletes directories, without me having ever accessed them, meaning they weren’t even in the history at that point, which allowed me to hit the ground running. I want that with zsh as well. Is there a plugin or something like that, which allows for these extra features, and can autosuggest commands from PATH and autocomplete directories? I really want to switch to a POSIX shell, but the lack of this feature would make it feel like quite a downgrade. Thanks.
Sorry, not an answer to your question, but what is it about non POSIX that frustrates you?
I type in a command without sudo, I prefer to type in a
sudo !!rather than to up arrow, then do Ctrl+A then type sudo and press Enter, for example. I wanted to install Nix earlier, but I needed to be in a POSIX shell for it to work, so I had to switch to bash for the installation. Those are just 2 examples from earlier today, and while you can learn to deal with them, it would juat be more effective to use a POSIX shell instead. It also means I can just set it as my login shell instead of having each of my terminal keybinds askitty -e fish, across all of my many window manager configs. Fish is faster, but I’m not sure if the cost is worthwhile.Fish has a hotkey for this built-in, just hit Alt + S.
The login shell troubles are very valid however. I worked around them by modifying my .bashrc to drop me into fish, and it has been working pretty well for me so far.
The linked solution also handles only launching fish if the parent process is not fish, so you can still access bash easily for when you really need it.
Thank you for your suggestions, but zsh has been treating me very well, so I think I’ll stick with it for now.
