Is there a way to get the git root directory in one command?

Question

Mercurial has a way of printing the root directory (that contains .hg) via

hg root

Is there something equivalent in git to get the director

Answer 1

To write a simple answer here, so that we can use

git root

to do the job, simply configure your git by using

git config --global alias.root "rev-parse --show-toplevel"

and then you might want to add the following to your ~/.bashrc:

alias cdroot='cd $(git root)'

so that you can just use cdroot to go to the top of your repo.
