How to undo several Git commands?
This question already has an answer here:
 To undo a specific commit from the last known good commit, first look at the git log and you should see this in the shell:  
commit: your40characterSHA1codehere # copy this into the clipboard
Author: your name here with email address
date: date-here
Commit message here
 You should copy the commit sha1 code, then perform git reset --hard your40characterSHA1codehere and git push origin master --force to force push the master or other branches you worked on.  Hope this helps!
