In my local environment I made several changes, then:
$ git log --oneline
2aa8998 Changes 02
5131bfe Changes 01
$ git commit -am "Commit 03"
$ git push
$ git log --oneline
9ca6c56 Changes 03
2aa8998 Changes 02
5131bfe Changes 01
But I noticed what I made a mistake, as I return to commit 2aa8998 before "git commit -am "Commit 03" with the changes without commit?
