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.

    I prefer to type in a sudo !! rather than to up arrow, then do Ctrl+A then type sudo and press Enter

    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.
