Full instructions for installing git can be found here.
With Mavericks or above, simply run the command git from Terminal.
You can also use an installer, found here.
Use the installer here.
Use the appropriate package manager for your flavour of Linux:
$ sudo yum install git-all
$ sudo apt-get install git-all
Set your name and email:
git config --global user.name "Jane Doe"
git config --global user.email [email protected]
If you're viewing this, you're probably already on GitHub.com. Go ahead and make an account!
Create a git repository using git init.
Inside your repository, use git status to check the current status of the "working tree" (any changes you've made, files you're tracking, etc.) You'll be on a branch called master. You should use this command very often.
Use git checkout -b <branch> to create and switch to a new branch named (pick your own branch name for this!)
Now, if you git status, you can see that you're on the new branch.
Go make some changes to the code in the repository. Add a file, change a line, etc.
Now, try git status.
You'll see that you have some unstaged changes! Add them to your staging area using git add <filename>.
You can also use git add . or git add -A to add all files in the directory, but this should be used with caution.
git status again and you'll see that the changes are now "staged".
Once you're happy with your changes, use git commit -m "Your message" to commit them! A commit is a record of changes in the repository. Later on, you'll be able to see your changes at each commit, and roll back to a previous commit if necessary.
Now that you have some commits on your branch, you may want to update your master branch.
