I have a directory, let’s call it ./src (because it is). This directory has several other directories of which some subset are git repositories. Updating them all by hand is tedious at best and I am lazy. Here’s a one-liner that will do all of the work for you.

W=`pwd`;for i in $(find . -name .git);do D=$i;D=${D%/*};cd $W/$D;pwd;git pull;done

This has the potential to be a bit taxing as well though if you need to enter credentials for every pull. We can solve that one as well.

git config --global credential.helper 'cache --timeout=[S]'

The --timeout option has a parameter, S, which is the timeout in seconds. This can be omitted and a default timeout of 15 minutes will be used.

Being lazy + saving time + making things easy = Happy Panda!
