Shell script to check multiple git repositories for updates.

update-gits.sh

#!/bin/bash

repos=( 
  "/Users/rob/Library/Application Support/TextMate/Bundles/Git.tmbundle"
  "/Users/rob/Library/Application Support/TextMate/Bundles/Ruby.tmbundle"
  "/Users/rob/Library/Application Support/TextMate/Bundles/RubyAMP.tmbundle" 
  "/Users/rob/Library/Application Support/TextMate/Bundles/Ruby Haml.tmbundle"
  "/Users/rob/Library/Application Support/TextMate/Bundles/Ruby on Rails.tmbundle"
  "/Users/rob/Library/Application Support/TextMate/Bundles/ruby-sass.tmbundle"
  "/Users/rob/Library/Application Support/TextMate/Bundles/ruby-shoulda.tmbundle"
)

echo "Checking" ${#repos[@]} "repositories for updates"

for repo in "${repos[@]}"
do
  echo "updating" ${repo}
  cd "${repo}"
  git pull
done

rather than adding entries to $repos manually, you can try "for dir in $(find . -name ".git")" .
