A while back i wrote a similar script which extracts the .PKGINFO file
from each package in one's cache. slow, but I think this is a more
accurate way to compare versions.
as-is, it will cp $N versions back from installed packages (inclusive)
to $WD/saveme, where N and WD are defined in the script.
i use it to save the N version, clean out my cache, then move them back.
but i think you could easily modify it to suit your usage case
instead of moving N versions to saveme you could echo the filename into
a saveme.lst, then mv anything not in saveme.lst to your oldpkg
directory.
or you could just take my little .PKGINFO / awk trickery and merge it
into your script...
or you could just ignore me and go with mod times :).
anyways, more info is always better, right? i've attached the script for
you to peruse.
thanks,
pat
