The last revision you checked out was 1.62, so you will by default diff against that version. CVS uses the static revision number not a "branch tag" like HEAD or RELENG_2_1_0 to determine the file to diff against for exactly the reason that they can change between updates of your checked out version. > moreover if no files are listed on the command line > then all files in the local directory (and below should be > diff'ed, but the are not. so "cvs diff" run while in > /sys/vm should diff every file in the directory, including > vm_page.c. but no output is displayed ;( > > If you don't specify any files, diff will display > differences for all those files in the current > directory (and its subdirectories, unless you use > the standard option -l) that differ from the corre- > sponding revision in the source repository (i.e. > files that you have changed), or that differ from > the revision specified. > > still confused ;( It did diff them all, but found nothing had changed. If you go in and hand modify any of those files, you will get diffs. If you specify "-r HEAD" you will see all of John's recent changes for example. > perhaps, i am not checking out and updating correctly? > initial command: cd /usr; cvs co -P src > to update: cd /usr; cvs update -P I think you're confusing things like "HEAD" and "RELENG_2_1_0" with actual revision numbers. Once you get that figured out, you're home free. >jmb -- Justin T. Gibbs =========================================== FreeBSD: Turning PCs into workstations ===========================================
