.Xc
 | 
						|
Displays properties for the given datasets.
 | 
						|
If no datasets are specified, then the command displays properties for all
 | 
						|
datasets on the system.
 | 
						|
For each property, the following columns are displayed:
 | 
						|
.Bl -tag -compact -offset 4n -width "property"
 | 
						|
.It Sy name
 | 
						|
Dataset name
 | 
						|
.It Sy property
 | 
						|
Property name
 | 
						|
.It Sy value
 | 
						|
Property value
 | 
						|
.It Sy source
 | 
						|
Property source
 | 
						|
.Sy local , default , inherited , temporary , received , No or Sy - Pq none .
 | 
						|
.El
 | 
						|
.Pp
 | 
						|
All columns are displayed by default, though this can be controlled by using the
 | 
						|
.Fl o
 | 
						|
option.
 | 
						|
This command takes a comma-separated list of properties as described in the
 | 
						|
.Sx Native Properties
 | 
						|
and
 | 
						|
.Sx User Properties
 | 
						|
sections of
 | 
						|
.Xr zfsprops 7 .
 | 
						|
.Pp
 | 
						|
The value
 | 
						|
.Sy all
 | 
						|
can be used to display all properties that apply to the given dataset's type
 | 
						|
.Pq Sy filesystem , volume , snapshot , No or Sy bookmark .
 | 
						|
.Bl -tag -width "-s source"
 | 
						|
.It Fl H
 | 
						|
Display output in a form more easily parsed by scripts.
 | 
						|
Any headers are omitted, and fields are explicitly separated by a single tab
 | 
						|
instead of an arbitrary amount of space.
 | 
						|
.It Fl d Ar depth
 | 
						|
Recursively display any children of the dataset, limiting the recursion to
 | 
						|
.Ar depth .
 | 
						|
A depth of
 | 
						|
.Sy 1
 | 
						|
will display only the dataset and its direct children.
 | 
						|
.It Fl o Ar field
 | 
						|
A comma-separated list of columns to display, defaults to
 | 
						|
.Sy name , Ns Sy property , Ns Sy value , Ns Sy source .
 | 
						|
.It Fl p
 | 
						|
Display numbers in parsable
 | 
						|
.Pq exact
 | 
						|
values.
 | 
						|
.It Fl r
 | 
						|
Recursively display properties for any children.
 | 
						|
.It Fl s Ar source
 | 
						|
A comma-separated list of sources to display.
 | 
						|
Those properties coming from a source other than those in this list are ignored.
 | 
						|
Each source must be one of the following:
 | 
						|
.Sy local , default , inherited , temporary , received , No or Sy none .
 | 
						|
The default value is all sources.
 | 
						|
.It Fl t Ar type
 | 
						|
A comma-separated list of types to display, where
 | 
						|
.Ar type
 | 
						|
is one of
 | 
						|
.Sy filesystem , snapshot , volume , bookmark , No or Sy all .
 |

.Xc
 | 
						|
Clears the specified property, causing it to be inherited from an ancestor,
 | 
						|
restored to default if no ancestor has the property set, or with the
 | 
						|
.Fl S
 | 
						|
option reverted to the received value if one exists.
 | 
						|
See
 | 
						|
.Xr zfsprops 7
 | 
						|
for a listing of default values, and details on which properties can be
 | 
						|
inherited.
 | 
						|
.Bl -tag -width "-r"
 | 
						|
.It Fl r
 | 
						|
Recursively inherit the given property for all children.
 | 
						|
.It Fl S
 | 
						|
Revert the property to the received value, if one exists;
 | 
						|
otherwise, for non-inheritable properties, to the default;
 | 
						|
otherwise, operate as if the
 | 
						|
.Fl S
 | 
						|
option was not specified.

.Sh EXAMPLES
 | 
						|
.\" These are, respectively, examples 1, 4, 6, 7, 11, 14, 16 from zfs.8
 | 
						|
.\" Make sure to update them bidirectionally
 | 
						|
.Ss Example 1 : No Creating a ZFS File System Hierarchy
 | 
						|
The following commands create a file system named
 | 
						|
.Ar pool/home
 | 
						|
and a file system named
 | 
						|
.Ar pool/home/bob .
 | 
						|
The mount point
 | 
						|
.Pa /export/home
 | 
						|
is set for the parent file system, and is automatically inherited by the child
 | 
						|
file system.
 | 
						|
.Dl # Nm zfs Cm create Ar pool/home
 | 
						|
.Dl # Nm zfs Cm set Sy mountpoint Ns = Ns Ar /export/home pool/home
 | 
						|
.Dl # Nm zfs Cm create Ar pool/home/bob
 | 
						|
.
 | 
						|
.Ss Example 2 : No Disabling and Enabling File System Compression
 | 
						|
The following command disables the
 | 
						|
.Sy compression
 | 
						|
property for all file systems under
 | 
						|
.Ar pool/home .
 | 
						|
The next command explicitly enables
 | 
						|
.Sy compression
 | 
						|
for
 | 
						|
.Ar pool/home/anne .
 | 
						|
.Dl # Nm zfs Cm set Sy compression Ns = Ns Sy off Ar pool/home
 | 
						|
.Dl # Nm zfs Cm set Sy compression Ns = Ns Sy on Ar pool/home/anne
 | 
						|
.
 | 
						|
.Ss Example 3 : No Setting a Quota on a ZFS File System
 | 
						|
The following command sets a quota of 50 Gbytes for
 | 
						|
.Ar pool/home/bob :
 | 
						|
.Dl # Nm zfs Cm set Sy quota Ns = Ns Ar 50G pool/home/bob
 | 
						|
.
 | 
						|
.Ss Example 4 : No Listing ZFS Properties
 | 
						|
The following command lists all properties for
 | 
						|
.Ar pool/home/bob :
 | 
						|
.Bd -literal -compact -offset Ds
 | 
						|
.No # Nm zfs Cm get Sy all Ar pool/home/bob
