20 Git Commands You Should Know


Git is a version control system developed in 2005 by Linus Torvalds, the creator of the Linux kernel. It helps you keep track of the code changes you've made to files in your project. It comes bundled with a large number of commands that you could use to efficiently manage your source code.
In this article, we'll go over the 20 most frequently needed Git commands that every software developer should know.

You could use the above command to switch to a newly created or a different branch.
