Fork a github repo, clone it, and set the upstream to the forked url

readme.md

Git Fork-Clone-Upstream

This python script is designed to fork a repository, clone it locally, and set the upstream url for the newly created repository to the original url. I found myself duplicating this task far too much, so this script should help reduce the amount of me doing all these tasks.

This is my initial steps to learning python.

How to use

$ python git-fork-clone-upstream.py https://github.com/jenkinsci/jenkins

It will fork the repo (if it isn't forked already), and clone it locally.

TODO:

• Read from ~/.github file with just the oauth token not need to set it as an environment variable. (done)
• Would be nice to have a message about failing to clone repo because directory already exists. (done)
• Might be better to have an argument instead of using os.environ. (done)
