When I’m wailing on a project in bash, I frequently find myself wanting to cd back to the project root. Since we use git, this is the same as the git_root directory. So I wrote a bash function that looped through the directories in the current path and found the one that contained the .git/ directory.

Luckily, I thought to ask on #git if there was an easier way before I posted my script (because no one likes to look like a noob on their own blog). It turns out there’s a one liner. I’ve posted it here, with a little padding so that I can feel like I made a contribution.

function gr {
    ## If the current working directory is inside of 
    ## a git repository, this function will change
    ## it to the git root (ie, the directory that 
    ## contains the .git/ directory), and then print
    ## the new directory.    
    git branch > /dev/null 2>&1 || return 1
    cd "$(git rev-parse --show-cdup)".
    pwd
}
