# Problem Statement: 
# You have mulitple copies (or clones) of upstream repositories in your local drive.
# Your local cloned repos need to be updated against the upstream master repos on a regular basis. 
# Here's one solution that uses the IPython notebook.

# Open up your IPython notebook browser in your working directory and then paste the following into a code cell. 
# Press SHIFT+ENTER to run the code cell. 

# Create a list of projects located in the working directory.
list_of_projects = ["django", "ipython", "oh-mainline"] 

def update_and_push_to_origin(folder):
    %cd {folder}
    !git checkout master
    !git fetch upstream
    !git stash #Stash any un-committed changes before you rebase against upstream master.
    !git rebase upstream/master
    print "Updating your origin master branch on Github."
    !git push origin master
    
# Iterate through each project in the array and update each project. 
for project in list_of_projects:
    print "\nCurrently updating the {!s} project.".format(project)
    print "-------------------------------------------------------------\n"
    update_and_push_to_origin(project)
    %cd ..
