You will need ssh keys if you want to upload code to repositories that use ssh authentication, such as Git Hub. If you do not already have an rsh public key, create one using
ssh-keygen. (This command is available in the Git Bash shell that is part of msysGit and is installed by default on OS X and most Linux and Unix systems.) You can just pick all the default options. Remember where
ssh-keygenputs your public key (id_rsa.pub) so that you can retrieve it when you need it. (Most likely the .ssh directory in your home directory.)
Next, you should configure your git client so that it knows who you are (your name and email address.)
git config --global user.name "First Last"
git config --global user.email "email@example.com"
(Note: If you use more than one email address or multiple nom de codes that you want to use, it is possible to set these to different values for specific projects.)
Next, create a local directory to hold your code. On Unix-like operating systems /usr/local/src or $HOME/src are conventional. For Windows, I recommend c:\code. But you can use anything you like.
Move to your code directory. Now you can create your first git repository named "test".
git init test
This creates a directory named "test" containing only the files necessary to manage git.
You can add files to this directory using your favorite text editor, development environment, or the file manager. For the purpose of this tutorial, create a file called "README" that explains what your project is about. Next you need to tell git about the file with:
git add README
(Note: you'll need to be in the test directory for this to work.)
Now you can look at your repository using
git statusand see the file:
# On branch master
# Initial commit
# Changes to be committed:
# (use "git rm –cached
..." to unstage)
# new file: README
At this point, git knows about the file, but it isn't officially part of the repository. To officially add the file to git, you need to use:
git commit -C 'Initial Version' README
The string after the -C is a comment that describes what the code is for or what changes have been made. You can review changes later by looking at these comments. Now if you look at
