Undoing

Undoing changes in your repo

• git mv <existing_path> <new_path>

  -Move (&/or rename) a file & stage move

• git rm <file>

  -Remove a file from the working directory & staging area, then stage the removal

• git rm --cached <file>

  -Remove from staging area only

• git checkout <commit_ID>

  -View a previous commit (READ only)

• git revert <commit_ID>

  -Create a new commit, reverting the changes from a specified commit

• git reset <commit_ID>

  -Go back to a previous commit & delete all commits ahead of it (revert is safer). Add --hard flag to also delete workspace changes (BE VERY CAREFUL)
