Question

I committed my work (note not pushed) in a known good state. I have since made unwanted local changes (without committing or pushing them). What is the command to undo these changes and revert to my previous commit state?

Please accept my apologies for the beginner question but the suggestions turned up by my googling seem arcane and I would like to be confident in my actions.

From Pro Git Commnuity book:

Fixing mistakes

If you’ve messed up the working tree,
but haven’t yet committed your
mistake, you can return the entire
working tree to the last committed
state with

$ git reset --hard HEAD
