问题
I made a bug fix on bug fix branch, but now I need to rollback all change on this branch. How to do that? I don't want to revert each file one by one, :(.
回答1:
I didn't test it recently, but check out the perl script available with a ClearCase installation called cset.pl (also available here):
ccperl cset.pl -undo myActivity
It should undo an activity by performing a negative merge (or substractive merge).
(That is, supposing you are using UCM since you are mentioning "changeset", which means "UCM activity")
