There isn’t much git work that you can’t do from within Magit but occasionally it’s convenient to call git directly. In another great tip from Wilfred Hughes’ Emacs Command of the Day we have:
Want to run a raw git command inside of @magit_emacs?
! ! (which is magit-git-command-topdir) inside a magit buffer.
This is really useful if you have custom git aliases, or if you want to use globbing (e.g. 'git rm -r old-dir*'). pic.twitter.com/kyjB34MpN1

You probably won’t use it often but it’s really nice to have the capability.
