This is a reference guide for those that are new to using git.
WHAT IS GIT
Git is a versioning control system.
WHAT TO CONTROL
Anything really. I personally use it for this site, personal code projects, backing up things ...
To get started you will first need to setup your git account. Then you can clone/push/pull files as need be.
This isn't going to a website necessarily to create and register. This is telling git some basics. Now, on fancier tools such as GitLab or GitHub, you can use your ssh public key for authenticating to your repos. But for less fancy things you will need to setup a email/password combination. Additional options are the editor used for the commit messages, and your diff tool. Some GUI tools can handle reading this in, and modifying them. I use only linux and the terminal for my tasks, so I can't speak for OSX/Windows GUI tools at all, and have only briefly used a few linux ones (GitCola, GitG).
git config --global user.name "John Doe" git config --global user.email email@example.com git config --global core.editor emacs git config --global merge.tool vimdiff
Check your settings:
git config --list
This will be the first pull done, presuming you have nothing and need to be current with whatever branch you are going to be working with. Some projects are utilizing multiple branches, others just one.
git clone URL_OF_REPO
As changes are made by those that have modification rights, you will obviously need to grab them. This is a pull.
If you were are someone who is authorized to make changes (commits), have made them, and would like to upload commits to the repo, this is called a push.
git add . git commit git push -u REPO BRANCH
Example to a GitLab repo:
git push -u origin master
I MUCKED SOMETHING UP AND CANNOT RE-PULL
Presuming you are using origin/master for your repo & branch
git fetch --all git reset --hard origin/master
