Git rebase is a process of moving or combining a sequence of commits to a new base commit. It is one of two Git utilities designed to integrate changes from one branch onto another. Rebasing is most useful when you want to incorporate changes from one branch into another branch with a linear history.
When you perform a Git rebase, you are rewriting history, changing the base of the developers branch from one commit to another, so it looks like they have created their branch from a different commit. Internally, Git creates a new commit and applies it to the specified base. However, its essential to understand that although the branch appears the same, its made up of entirely new commits.
Git rebase can be used to rearrange the order of commits, squash multiple commits into a single commit, and split a large commit into smaller ones. There are six commands available while rebasing: pick, reword, edit, squash, fixup, and exec.
In summary, Git rebase is a powerful tool that allows developers to integrate changes from one branch onto another with a linear history. It can be used to rearrange, combine, or split commits, and its essential to understand that it rewrites history.
