Best practice in science is to use version control when doing any programming. To use Git version control, go to the root directory of your folder of interest and create a new repository with:
git init
You can read more about this workflow with the GitHub interactive tutorial and the Software Carpentry lesson.
git push gives fatal: HTTP request failed
GitHub recommends using HTTPs when pushing to their repo. However on the HPC Cluster, this returns an error:
$ git push -u origin master error: The requested URL returned error: 403 Forbidden while accessing https://github.com/<username>/<repo>.git/info/refs fatal: HTTP request failed
To get around this, one should instead use git@ instead of https:// and : instead of the trailing / in github.com. You can do both these things but just running this command in the root of your git repo:
sed -ie '/url[ \t]*=[ \t]*/s/https:\/\/github.com\//git@github.com:/' .git/config grep url .git/config # See the change
Alternatively, when cloning the repository just use ssl instead:
$ git clone git@github.com:<user>/<repository>.git
git push gives Permission denied (publickey)
$ git push -u origin master Warning: Permanently added 'github.com,192.30.252.130' (RSA) to the list of known hosts. Permission denied (publickey). fatal: The remote end hung up unexpectedly
Follow the GitHub instructions to setup your ssh keys and add the public key to your GitHub repository.
