tig. “Tig is an ncurses-based text-mode interface for git.”
Just install it and you will see. After you will install it you will never
need any Git interfaces, just command line and tig.
ncdu. “Ncdu is a disk usage analyzer with an ncurses interface.”
There are plenty tools in App Store on OSX which allows you to track what is
taking so much space on your disk. But ncdu is free, works in terminal
and better than others.
