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

184 .Ss Example 1 : No Creating a ZFS File System Hierarchy
185 The following commands create a file system named
187 and a file system named
191 is set for the parent file system, and is automatically inherited by the child
193 .Dl # Nm zfs Cm create Ar pool/home
194 .Dl # Nm zfs Cm set Sy mountpoint Ns = Ns Ar /export/home pool/home
195 .Dl # Nm zfs Cm create Ar pool/home/bob

198 The following command disables the
200 property for all file systems under
202 The next command explicitly enables
206 .Dl # Nm zfs Cm set Sy compression Ns = Ns Sy off Ar pool/home
207 .Dl # Nm zfs Cm set Sy compression Ns = Ns Sy on Ar pool/home/anne
209 .Ss Example 3 : No Setting a Quota on a ZFS File System
210 The following command sets a quota of 50 Gbytes for
212 .Dl # Nm zfs Cm set Sy quota Ns = Ns Ar 50G pool/home/bob

280 The following command causes
281 .Ar pool/home/bob No and Ar pool/home/anne
284 property from their parent.
285 .Dl # Nm zfs Cm inherit Sy checksum Ar pool/home/bob pool/home/anne

294 The following commands show how to set
296 property options to enable read-write
297 access for a set of IP addresses and to enable root access for system
302 .Dl # Nm zfs Cm set Sy sharenfs Ns = Ns ' Ns Ar rw Ns =@123.123.0.0/16:[::1],root= Ns Ar neo Ns ' tank/home
