I want to be able to do a 'p4 describe' on all the changelists that will be copied upon a 'p4 copy' command. How can this be done?
I could do something like:
p4 copy -n from-branch/... to-branch/... | sed -e 's|.* ||' | xargs -n 1 p4 filelog
to find the list of changes per file and truncate the list at the point of the last branch or integrate action into to-branch (if there is one). But this could potentially take a long time. Is there a better way?
