git: a quick command to go to root of the working tree

Question

I wanted a simple git command to go up to the "root" of the repository.

I started with a script, but figured that I cannot change active directory of the shell, I had to do a function. Unfortunately, I cannot call it directly with the non-dash form "git root", for instance.

function git-root() {  if [ -d .git ]; then   return 0  fi   A=..  while ! [ -d $A/.git ]; do    A="$A/.."  done  cd $A } 

Do you have a better solution? (the function has been written quickly, suggestions are welcome)

Answer 1

This has been asked before, Is there a way to get the git root directory in one command? Copying @docgnome's answer, he writes

cd $(git rev-parse --show-cdup) 

Make an alias if you like:

alias git-root='cd $(git rev-parse --show-cdup)'
