The recommended practice for `.Os` on FreeBSD is to not specify any arguments. The correct OS name is used automatically. Oddly enough, on the Linux distro I tested this on (CentOS 7), the man pager defaulted to displaying "BSD" as the OS rather than "Linux". To accommodate this, tack " Linux" back on in an install hook on Linux. This is much simpler than removing it for FreeBSD when vendored in the base system.

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 .

|
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.
|

|
|
Recursively inherit the given property for all children.
|
|
