Git

2018/05/09

Git is a version control system used to track changes in computer files and to coordinate work among multiple users.
After installing Git you can initialize a repository:

$ git init

or alternatively, clone an existing repository:

$ git clone https://github.com/al1973/piecemeal.git

As an example, add three new files and then commit them to the repository:

$ git add one two three
$ git commit -m 'First commit'

You get a master branch pointed to by HEAD:

Create a new branch called testing:

$ git branch testing

Switch to the testing branch:

$ git checkout testing

Now HEAD points to the testing branch.
Do another commit:
Switch back to the master branch:

$ git checkout master

Make another change and commit:
When you are ready you can merge the 2 branches together.
Use the merge command to combine the testing branch with the master branch and then delete the testing branch:

$ git merge testing
$ git branch -d testing
