No, it would not for 3 reasons:

a) Addition of directories to the cvs repository would not exist in the
   checked out tree so the ``cvs update pathname'' would fail.

b) Removal of files/directories from the cvs tree cause the files to
   go into Attic subdirectories, the above would serious fail there
   (some massaging and adding the -P option to the cvs udpate command
   could fix this).

c) Other problems I haven't though of yet.

This is not to say that the desired results could not be obtained, but
it is a fair bit more complex than the above 1 line script.

I don't run ctm, but here is a better filter to replace the above
``awk '{print $NF}' with (this is written for sup -v >&logfile):

/\/Attic\// {
        next;
        }
/CVSROOT\// {
        next;
        }
/^SUP Receiving file / {
        print $NF;
        }
/^SUP Deleted file / {
        print $NF;
}

Then a little massaging with sed to rip off the filename components and
a pass through sort -u to get down to just the directories you need to
update, and finally a script that checks how far down a hierachy it can
cd before running a cvs update -P and you have your desired results.
