There is probably a simple solution to the problem I have. What I want to do is to copy only the new or newer (according to date/time) files from one location to another. I tried cp and couldn't do it. Then I tried zip with the update option on. That kind of worked but it copies packages as folders (not sure if that is a problem though). If there an easy way to do it? Thanks.

How do you define "new or newer"?

Rsync is made explicity for that purpose. Alternately, you could roll your own with a combination of somehting like 'find -ctime xxxx -exec cp {} dest/'

New: a file in the source not in the destination
Newer: a file in the source that is newer than it's copy in the destination

It made sense to me

I seriously need to get a Unix book. Does anyone think the release of OS X 10.3 will introduce many changes to the terminal command list? Any good Unix books for beginners?

Thanks...I'll give it a try.

not a cli solution, but deja vu will do just that, however it requires a folder to be copied -- won't do a single file.

I have deja vu doing all my backups in mirror mode - it is wonderful.

Oreilly's Learning Unix for Mac OS X is really good.

Thanks...I'll try Deja Vu and probably buy it. I'll probably get that book too after I check if my wife wants ny books of her own (save on shipping).

does rsync also work for volumes mounted with smb? the one i'm using here is a volume from an nt-server that i can only access via netlogon. i'm a bit hesitant to just try, in case some other person's data get's lost.

rsync has a "dry run" mode where it will connect to the volume (or remote server) and check to see which files would be moved, but it will not move any files nor otherwise make any changes to files/volumes. If it can't talk to the volume, the dry run will fail.
