101 If no datasets are specified, then the command displays properties for all
102 datasets on the system.
103 For each property, the following columns are displayed:
104 .Bl -tag -compact -offset 4n -width "property"
113 .Sy local , default , inherited , temporary , received , No or Sy - Pq none .
116 All columns are displayed by default, though this can be controlled by using the

200 .Ss Example 1 : No Creating a ZFS File System Hierarchy
201 The following commands create a file system named
203 and a file system named
207 is set for the parent file system, and is automatically inherited by the child
209 .Dl # Nm zfs Cm create Ar pool/home
210 .Dl # Nm zfs Cm set Sy mountpoint Ns = Ns Ar /export/home pool/home

222 .Dl # Nm zfs Cm set Sy compression Ns = Ns Sy off Ar pool/home
223 .Dl # Nm zfs Cm set Sy compression Ns = Ns Sy on Ar pool/home/anne
