So… I hate Perforce. I really do. It’s crap.
For example, it’s a super hassle to list all the changes submitted between two changelists. There is a p4 changes command, but the syntax is … derp. What I wanted was all the changes between changelist X and Y. Then I realized Y was basically ‘right now’, so I adjusted my target a little. After much guessing, I figured out all the changes between changelist X and now, excluding pending:
p4 changes -s submitted //depot/path/whatever/…’@>X’
Assuming X is a known changelist number, that would get you everything from X to now. Probably you could change the end of that to be @X,@Y and get between X and Y. I’m not sure, but if I find out, I’ll tell ya ;)
