Discard all and get clean copy of latest revision?

Question

I\'m moving a build process to use mercurial and want to get the working directory back to the state of the tip revision. Earlier runs of the build process will have modified so

Answer 1

To delete untracked on *nix without the purge extension you can use

hg pull
hg update -r MY_BRANCH -C
hg status -un|xargs rm

Which is using

update -r --rev REV revision

update -C --clean discard uncommitted changes (no backup)

status -u --unknown show only unknown (not tracked) files

status -n --no-status hide status prefix
