Git Adding a File to a Previous Commit

Posted on: 2014-12-06

Imagine that you are doing a commit and you forgot to bring a file or multiples files. You can do a second commit but this would have the consequence to have two commits for something that in fact would have been in one. Git allows you to alter a past commit with the amend parameter.

For example, here is a small commit of 1 file.

 git add main.cs git commit -m "This is my first commit" 

This is how to add a second file to this first commit.

 git add util.cs git commit --amend --no-edit 

The --no-edit parameter specify that we do not want to modify the message. If you are doing a git log, you will see a single commit.
