Git rebase is a fundamental command in Git used to integrate changes from one branch into another by moving or combining commits. Unlike merging, which creates a new commit to combine histories, rebasing rewrites the commit history to produce a linear sequence of commits. Essentially, it allows developers to change the base of their branch from one commit to another, making it appear as if the branch was created from a different starting point. Rebasing is often described as a “linear” way of combining commits because it avoids the complex…
