gitk

Gitk is a graphical user interface (GUI) tool for viewing and manipulating the commit history in a Git repository. It is a built-in tool that comes with Git and provides a visual representation of the commit graph, branches, tags, and diffs.

Some key features of gitk include:

1. Commit History: Gitk displays a graphical visualization of the commit history, showing the relationships between commits and their branch paths.

2. Branches and Tags: It allows you to view and manage branches and tags in the repository. You can create, delete, and merge branches, as well as create and delete tags.

3. Interactive Diffs: Gitk provides a side-by-side diff view of changes between different commits, allowing you to inspect and understand the differences in a visual manner.

4. Annotate Blame: It includes the ability to track the history of individual lines within a file, also known as git blame or git annotate. This feature helps understand who made specific changes to a file and when.

5. Filtering and Sorting: Gitk allows you to filter commit history based on various criteria such as author name, commit message, or timeframe. You can also sort the commits based on different fields like date, author, or commit message.

6. Interactive Rebasing: Gitk includes a feature called "Edit commit" which enables interactive rebasing. This allows you to modify and reorganize commits in a branch interactively.

Gitk operates as a standalone application launched from the command line or Git terminal. It provides a visual way to navigate and analyze the history of Git repositories, making it easier to understand and manage changes within a project.
