Coursera - The Data Scientist's Toolbox - Week 2 - Introduction to Git

"Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later."

Why is version control important?

Many of us constantly create something, save it, change it and then save it again. Version (or revision) control is a means of managing this process in a reliable and efficient way. It is especially important when collaborating with others.

"Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency."


You can download Git here.

Open Terminal. Now it's time to configure your username and email. Each commit to a Git repository (repo) is tagged with the username of the person who made the commit.

    $ git config --global "Firstname Lastname"
    $ git config --global ""

You only have to type this once and can always change these later using the same commands.

To confirm your changes:

$ git config --list

You can exit Terminal by typing

$ exit
