Fish Shell

a command line shell for the 90s!

tl;dr - sudo apt install fish; fish; fish_config

The Fish shell looks like bash but has a couple nice features.

• auto complete - fish will give recomended auto completion
• try to cd /etc and look around your directories, use tab and arrow keys

Make your own fish functions

You can make any fish function if you write it in a .fish file under ~/.config/fish/*

Here is my favorite git helper function written in fish

function commit –description “add, commit, and push in one line”
git add –all git commit -m “$argv” git push end

Manage your path

Because fish is a different shell than bash, any manual edits to your path (like in your .bashrc) will not be reflected in the fish shell. You should add a .fish file in .config/fish/ that adds these directories to your path. This will be needed for the dotnet cli and snaps.
