GIT: Any way to commit on multiple repos?

why don't you use something like this:

#!/bin/bash
for DIR in `ls`;
do
    if [ -d $DIR/.git ];
    then
            echo "updating location: " $DIR;
            cd $DIR
            # your commands here...
            git add -u 
            git add .
            git commit -m 'Latest'

            cd ..
    fi
done

Maybe you are looking for something like mr (homepage). I use it to update a bunch of repos all at once, but it can be configured to do any stuff you want. It's also available as Ubuntu and Debian package in official repos. Otherwise you can just write a script that does the stuff for you.
