Script to go into every subdir with a .git folder and pull latest changes from all branches/tags via git up. To use you might need to run 'gem install git up' - if you just want to get master use the original fork ;)

update_git_repos.sh

#!/bin/bash

# store the current dir
CUR_DIR=$(pwd)

# Let the person running the script know what's going on.
echo "\n\033[1mPulling in latest changes for all repositories...\033[0m\n"

# Find all git repositories and update it to the master latest revision
for i in $(find . -name ".git" | cut -c 3-); do
    echo "";
    echo "\033[33m"+$i+"\033[0m";

    # We have to go to the .git parent directory to call the pull command
    cd "$i";
    cd ..;

    # finally pull
    #git pull origin master;
    git up

    # lets get back to the CUR_DIR
    cd $CUR_DIR
done

echo "\n\033[32mComplete!\033[0m\n"
