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.

History of a file


As described in the Whole-tree commits section at the beginning of this chapter, in Git revisions are about the state of the whole project as one single entity.

In many cases, especially with larger projects, we are interested only in the history of a single file, or in the history limited to the changes in the given directory (in the given subsystem).

Path limiting

To examine the history of a single file, you can simply use use git log <pathname>. Git will then only show all those revisions that affected the pathname (a file or a directory) given, which means those revisions where there was a change to the given file, or a change to a file inside the given subdirectory.

Tip

Disambiguation between branch names and path names

Git usually guesses what you meant by writing git log foo; did you meant to ask for the history of branch foo (line of development), or for the history of the file foo. However, sometimes Git can get confused. To prevent confusion between pathnames...
