Update all git repos via cmd line in a subdir

This one is just for me so I don't forget this "one-liner". Updates all git repositories in direct subdirectories. Works on OS X :)

cwd=$(pwd); for dir in $(find . -type d -not -name '\.*' -maxdepth 1 -print); (current_dir="$cwd/${dir##./}"; echo "Updating $current_dir"; cd $current_dir; git pull --all;)
