Version Control:

When working alone there are many ways to manage files. However when collaborating with other developers on the same project it is important to be able to merge and resolve conflicts quickly and easily. Git allows a team to work together, track changes, branch off to work on new ideas and suggest changes with pull requests.

Command Line:

Although the command line is not visually rich and can be unintuitive, it is concise and powerful. It requires fewer resources than a graphical interface and common tasks can actually be faster to perform or even saved as scripts.


GUI:

Programs like Tower include a graphical user interface to manage git repositories.
