git rebase -i ca83eb3
When the interactive rebase happens, your text editor will come up. change pick
to drop
for the five commits you made. This will drop the commits from history after you save and exit the editor.
Of coarse we could do some bash with logging the sha with only commits from you on that day, but since it is only 5 commits, let's just do this easy rebase.
BUT:
You should not do this. Now that your commits are public, every developer’s code will have to be reset once you change history of their remote. Instead, consider leaving it, or making an additional commit that removes your code. You don't want to change history on public branches.
