fish, the friendly interactive shell, is a commandline shell intended to be interactive and user-friendly.
fish is intentionally not fully POSIX compliant, it aims at addressing POSIX inconsistencies (as perceived by the creators) with a simplified or a different syntax. This means that even simple POSIX compliant scripts may require some significant adaptation or even full rewriting to run with fish.
While using the fish shell you can just type ‘help’, and it’ll pull up an offline web page with their manuals and guides. But to be honest, I dont really use fish for anything but the fancy colors and auto-completion lol. Also fish 🐟 :)
oh yeah! the autocompletion seems great
