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 On 08/25/09 at 12:51am, David C.

The script for finding and moving older duplicate packages is named fduppkg and is fairly self-explanitory. Running without arguments gives the options:
BASH never fails to amaze me, 3116 element array to handle the packages, and BASH never batted an eye. It just kept on trucking....
