#Git Interactive Rebase

Scenario: We have a topic branch we've been working on. We want to combine the last few commits into one single commit. Our intention is to merge this topic branch, with one clean commit, into our main dev branch.

Solution: Git Rebase Interactive

Checkout your topic branch and look at your commit history:

$ git checkout topic-branch

todgru

#git rebase -i <sha>

List of commits from git log

F--E--D--C--B--A

Lets say you want to remove commit D from the commits.

git rebase -i E
