What is the purpose of the git rebase command in version control workflows?

The git rebase command is used to move or 'rewrite' a series of commits onto a new base. Its main purpose is to make the commit history more linear and clean, which facilitates understanding and integrating changes.

For example, if you are working on a feature branch that is behind the main branch master, you can execute:

git checkout feature
git rebase master

This will move your commits on top of the latest commits from master, as if you started working on the current version.

Advantages of git rebase:

• Simplifies history by avoiding unnecessary merge commits.
• Allows integrating changes from the main branch before merging.

Important: when using rebase on public branches, be careful not to rewrite history that others are already using.
