Listing most recent ZFS snapshots

Question

I am regularly taking ZFS snapshots for 30 Virtual Machines (VMs) for 20 versioning of times.

My list of snapshots is for only two VMs:

How can I list only the LATEST taken snapshots for all VMs to check the latest snapshot which was taken?

Answer 1

The latest taken snapshot could be obtained with this:

zfs list -t snapshot -o name,creation -s creation | tail -n1

If using capital -S sorts by property in descending, returning, in this case, the first taken snapshot:

zfs list -t snapshot -o name,creation -S creation | tail -n1
