Mercurial: How do you undo changes?

Question

When using Mercurial, how do you undo all changes in the working directory since the last commit? It seems like this would be a simple thing, but it\'s escaping me.

Answer 1

hg revert is your friend:

hg revert --all 

hg update merges your changes to your current working copy with the target revision. Merging the latest revision with your changed files (=current working copy) results in the same changes that you already have, i.e., it does nothing :-)

If you want to read up on Mercurial, I'd recommend the very awesome tutorial Hg Init.
