Rollback to last git commit

Solution 1:

Caveat Emptor - Destructive commands ahead.

Mitigation - git reflog can save you if you need it.

1) UNDO local file changes and KEEP your last commit

git reset --hard

2) UNDO local file changes and REMOVE your last commit

git reset --hard HEAD^

3) KEEP local file changes and REMOVE your last commit

git reset --soft HEAD^

Solution 2:

If you want to remove newly added contents and files which are already staged (so added to the index) then you use:

git reset --hard

If you want to remove also your latest commit (is the one with the message "blah") then better to use:

git reset --hard HEAD^

To remove the untracked files (so new files not yet added to the index) and folders use:

git clean --force -d

Solution 3:

git reset --hard will force the working directory back to the last commit and delete new/changed files.
