# AUTOMATE UPDATING ALL PROJECTS
#
# Problem: going to each project and then pulling changes.
# Solution: Automate git pulling for all my projects
#
# 1. Create a pull_projects file and add the code from this gist
# 2. Move the file into a directory that is in your path, i.e. $PATH
# 3. Make the file executable, eg. chmod +x /usr/local/bin/pull_projects
