Hi Harry,


Simplest option would be something like

zfs list -t snapshot -o name -H -r filesystem/path > /tmp/snaplist.txt

edit /tmp/snaplist.txt to remove the snapshot you want to keep

for SNAP in `cat /tmp/snaplist.txt`
do
	zfs destroy $SNAP
done

My syntax may be a little off with the for loop but I'm sure you get the
idea.

Cheers

Tim
