Overview of this book

Git is one of the most popular types of Source Code Management (SCM) and Distributed Version Control System (DVCS). Despite the powerful and versatile nature of the tool enveloping strong support for nonlinear development and the ability to handle large projects efficiently, it is a complex tool and often regarded as “user-unfriendly”. Getting to know the ideas and concepts behind the architecture of Git will help you make full use of its power and understand its behavior. Learning the best practices and recommended workflows should help you to avoid problems and ensure trouble-free development. The book scope is meticulously designed to help you gain deeper insights into Git's architecture, its underlying concepts, behavior, and best practices. Mastering Git starts with a quick implementation example of using Git for a collaborative development of a sample project to establish the foundation knowledge of Git operational tasks and concepts. Furthermore, as you progress through the book, the tutorials provide detailed descriptions of various areas of usage: from archaeology, through managing your own work, to working with other developers. This book also helps augment your understanding to examine and explore project history, create and manage your contributions, set up repositories and branches for collaboration in centralized and distributed version control, integrate work from other developers, customize and extend Git, and recover from repository errors. By exploring advanced Git practices, you will attain a deeper understanding of Git’s behavior, allowing you to customize and extend existing recipes and write your own.

Multiple working directories


Git for a long time allowed to specify where to find the administrative area of the repository (the .git directory) with the git --git-dir=<path> <command>, or the GIT_DIR environment variable, making it possible to work from the detached working directory.

To be able to reliably use multiple working directories sharing a single repository, we had to wait until version 2.5 of Git. With it, you can create a new linked work tree by using git worktree add <path> <branch>, allowing us to have more than one branch checked out. For convenience, if you omit the <branch> argument, then a new branch will be created based on the name of the created worktree.

Note

If you use an older Git version, there is always the git-new-workdir script, which can be found in the contrib/ area of the Git project repository. It is however, Unix-only (it relies on symbolic links), and is somewhat fragile.

This mechanism can be used instead of git stash if you need...
