Only some properties can be edited.
See
.Xr zfsprops 8
for more information on what properties can be set and acceptable
values.
Numeric values can be specified as exact values, or in a human-readable form
with a suffix of
.Sy B , K , M , G , T , P , E , Z
.Po for bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, exabytes,
or zettabytes, respectively
.Pc .
User properties can be set on snapshots.
For more information, see the
.Em User Properties
section of
.Xr zfsprops 8 .

.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:
.Bd -literal
    name      Dataset name
    property  Property name
    value     Property value
    source    Property source  \fBlocal\fP, \fBdefault\fP, \fBinherited\fP,
              \fBtemporary\fP, \fBreceived\fP or none (\fB-\fP).
.Ed
.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
.Em Native Properties
and
.Em User Properties
sections of
.Xr zfsprops 8 .
.Pp
The value
.Sy all
can be used to display all properties that apply to the given dataset's type
.Pq filesystem, volume, snapshot, or bookmark .
.Bl -tag -width "-H"
.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.
.Sy name Ns \&, Ns Sy property Ns \&, Ns Sy value Ns \&, Ns Sy source
is the default value.
.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 ,
.Sy default ,
.Sy inherited ,
.Sy temporary ,
.Sy received ,
and
.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 ,
.Sy snapshot ,
.Sy volume ,
.Sy bookmark ,
or
.Sy all .
.El
.It Xo
.Nm
.Cm inherit
.Op Fl rS
.Ar property Ar filesystem Ns | Ns Ar volume Ns | Ns Ar snapshot Ns ...
.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 8
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 operate as
if the
.Fl S
option was not specified.
