Git Push command
The git push sub command is how to go about updating a remote with local changes. Of course in order to do this to begin with one will need to set up a remote repository to begin with. So with that said there is also knowing at least a thing or two about the git remote command as a way to find out if any remotes are set up to begin with, and if need be to add one.
I also wrote a blog post on the git pull command which does seem to be more or less the counter part of the git pull command, or at least one of them anyway. I say that because there is also the git fetch command as well is a litter different. However in any case there is pulling down changes from a remote, and thus updating the local git folder, and then there is pushing local changes to the remote.
