Lazygit: Simple terminal UI for Git commands(github.com)

  git commit --fixup=':/message regexp'

    git add file1
    git commit -m "Fix some bug in file1"
    git add file2
    git commit -m "Add a feature flag for file1"
    # Oh no, first commit was borked, need to fix it
    git add file1
    git absorb
    # this will now automatically create one or more fixup commits
    git rebase -i --autosquash $(git merge-base master)
    # voila, tidy history and each commit works
