Git: Mastering Version Control

Redo – recreate the latest commit with new changes

As with undo, redo can mean a lot of things. In this context, redoing a commit will mean creating almost the same commit again with the same parent(s) as the previous commit, but with different content and/or different commit messages. This is quite useful if you've just created a commit but perhaps have forgotten to add a necessary file to the staging area before you committed, or if you need to reword the commit message.

Getting ready

Again, we'll use the hello world repository. Make a fresh clone of the repository, or reset the master branch if you have already cloned.

We can create a fresh clone as follows:

$ git clone https://github.com/dvaske/hello_world_cookbook.git
$ cd hello_world_cookbook ...
