Pushing to Multiple Remote Repositories at Once

If you want to push to multiple remote repositories using a single name you can first add the two remotes separately and then end .git/config to add a third remote that combines both of them together:
[remote "heroku"]
 url = git@heroku.com:bnd-notes.git
 fetch = +refs/heads/*:refs/remotes/heroku/*
[remote "github"]
 url = git@github.com:buildndeploy/notes.git
 fetch = +refs/heads/*:refs/remotes/github/*
[remote "external"]
    url = git@github.com:buildndeploy/notes.git
 url = git@heroku.com:bnd-notes.git
 fetch = +refs/heads/*:refs/remotes/heroku/*
Then you can update them with a single command:
$ git push external


git stash / git stash save
git stash list
git stash apply <stash>
git stash apply stash@{0}
git stash pop

GitHub Fork Merge
