ZFS list rough cheatsheet

Accurately list used space for specific queries, such as each snapshot or each dataset, using `zfs list`

List & sort ascending only total used space by all snapshots of individual datasets:

zfs list -r -o name,usedsnap -s usedsnap

List & sort ascending actual disk usage = disk usage from specific dataset without children dataset’s storage

zfs list -r -o name,usedds -s usedds
zfs list -ro space

-s [column name] sorts zfs list output in ascending order by selected column’s data, -S [column name] sorts the same descending.
