Hi Don,

Sorry for the confusion, this is part of a script that was created by someone who no longer works here, and I was trying to use part of the functionality in a new script that I was creating.

I've managed to modify it using

Code:

FILENAME=$(ssh ${DEST_SERV} "ls ${DEST_LOCATION}/${FILES} | sort -r -k 4n | head -1")

which is then followed with

Code:

ssh ${DEST_SERV} "ls ${DEST_LOCATION}/${FILES} | grep -v ${FILENAME} | xargs rm -rf"

to remove the unwanted files.

I was confused with what the

Code:

4,4n

was doing, but your explanation has helped with this, although I still don't understand what the 4 before the comma is doing.

Thanks for your help.
