Remove Recent Commits from a Git Repo

I’ve been building a workshop that uses the Spring Petclinic example application.

I’ve made two commits updating the welcome message, and I’ve pushed those commits to a repo in github, but now I want to remove them.

Here are the commits:

$ git log
commit 9fec5226ec3dbc900bf3939c10f7f5e2b3c5ee94 (HEAD -> main, origin/main, origin/HEAD)
Author: curtis <curtis@serverascode.com>
Date:   Tue Aug 11 21:30:01 2020 -0400

    update welcome

    change welcome message

    Polish
SNIP!

As you can see above there are two commits, 9fec5226ec3dbc900bf3939c10f7f5e2b3c5ee94 and 405d7567681871bd04439c2f49e13f96a0816d27 and I want to remove them from the remote repo.

It’s actually quite easy! I’m going to reset to the commit prior to my two commits, c42f95980a943634106e7584575c053265906978.

$ git reset --hard c42f95980a943634106e7584575c053265906978
HEAD is now at c42f959 remove push-to-pws button from guide, since pws free trials end

Now git log shows…

$ git log
