12 Excellent Free Books to Learn Git

Last Updated on April 27, 2023

Revision control is a practice that tracks and provides control over changes to source code. It is a critical tool in the developer’s tool chain. Git is a distributed revision control system initially designed and developed by Linux Torvalds for Linux kernel development. It is used on many kernel-related projects besides the Linux kernel such as OpenVZ, KVM, ALSA, and udev. Git is also frequently used for source code management for non-kernel projects.

Git is the most widely used version control system, in part because of the popularity of GitHub, a web-based Git repository hosting service, which offers all of the distributed revision control and source code management) functionality of Git as well as adding its own features.

Git is a popular choice for revision control because it is fast, stable, flexible, and extremely powerful. It offers a comprehensive feature set, an active development team, and a number of free hosting communities. It’s a reliable versatile multipurpose revision control tool whose extraordinary flexibility makes it tricky to learn, let alone master. Hence the need for some great free books.

The books featured in this article are all available for free, and many of them are released under an open source license. Some of the text are designed for beginners, others help developers get to grip with the somewhat ugly internals of Git. So get reading, learning and sharing code.
