First thing I do for any *nix install is immediately install Fish. Like many younger computer users I prefer rainbow barf.
I tried fish and really liked it until I tried to run one of my numerous helper scripts and was faced with syntax error; too lazy to update so many scripts.
Same for me, later I switched back to zsh after I discovered this plugin:

Best of both world really.
