thanks chris.
i have now got a script going to copy newly added files thanks to the
people on this list. my next step is to try and activate the script
using a time scheduling application like "T-Minus Ten" and seeing if
i can get the script to check folders on the network for new files
which have come in and copy them to a folder on my hard drive.
i have got OS9 at my work so the folder would have to be open. i
don't quite understand how the folder action would work though in
terms of what i want to do which is:
a) to mount shared disks on the network on to my desktop
b) periodically (say twice a day) check certain folders on the shared
disks for newly added files
c) copy the newly added files to a folder on my desktop and
d) do various kinds of processing on the files
still i will definitely pursue the folder actions line of inquiry
further if my present course of action turns out to be a dead end.
thanks again

a newbie query about lists:
If I have two lists
list1 {"1","2","3"}
list2 {"1", "2", "3", "4"}
what i want to do is:
1) loop through both lists
2) get a list of those items which are in list2 but not in list1
3) copy the missing items from list2 to list1
What I eventually want to do is to have a script which checks a
folder (list2) periodically for newly added files (like "4") and
copies any newly added files to another folder (list1).
While it's certainly possible to do this yourself, it's also one of
the things Folder Actions was designed for. Just attach a script
with an "on items added" handler to the appropriate folder, and it
will get called with the appropriate items. If you're using Mac OS
X 10.2, the easiest way to do this is to install Script Menu and
then use the Folder Action commands.
(Now the fine print: Folder Actions don't exist on 10.0 and 10.1.
In Mac OS 9, they only work if the folder's window is open.)
