Git Push to Two Repositories at the Same Time

Suppose You have 2 repositories:

https://github.com/synckey/synckey.github.io.git
https://git.coding.net/synckey/synckey.git

You want to push to them within one command.

# if your project is cloned from this repository, 
# you can simply ignore this first command
git remote add origin https://git.coding.net/synckey/synckey.git
git remote set-url --add https://git.coding.net/synckey/synckey.git

Then if you want to push to both of them, just rum git push as normal.
