65Only some properties can be edited.
66See
67.Xr zfsprops 8
68for more information on what properties can be set and acceptable
69values.
70Numeric values can be specified as exact values, or in a human-readable form
71with a suffix of
72.Sy B , K , M , G , T , P , E , Z
73.Po for bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, exabytes,
74or zettabytes, respectively

92Displays properties for the given datasets.
93If no datasets are specified, then the command displays properties for all
94datasets on the system.
95For each property, the following columns are displayed:
96.Bd -literal
97    name      Dataset name
98    property  Property name
99    value     Property value
100    source    Property source  \fBlocal\fP, \fBdefault\fP, \fBinherited\fP,
101              \fBtemporary\fP, \fBreceived\fP or none (\fB-\fP).
102.Ed
103.Pp
104All columns are displayed by default, though this can be controlled by using the
105.Fl o
106option.
107This command takes a comma-separated list of properties as described in the
108.Em Native Properties
109and
110.Em User Properties
111sections of
112.Xr zfsprops 8 .
113.Pp
114The value
115.Sy all
116can be used to display all properties that apply to the given dataset's type
117.Pq filesystem, volume, snapshot, or bookmark .
118.Bl -tag -width "-H"
119.It Fl H
120Display output in a form more easily parsed by scripts.
121Any headers are omitted, and fields are explicitly separated by a single tab
122instead of an arbitrary amount of space.
123.It Fl d Ar depth
124Recursively display any children of the dataset, limiting the recursion to
125.Ar depth .
126A depth of
127.Sy 1
128will display only the dataset and its direct children.
129.It Fl o Ar field
130A comma-separated list of columns to display.
131.Sy name Ns \&, Ns Sy property Ns \&, Ns Sy value Ns \&, Ns Sy source
132is the default value.
133.It Fl p
134Display numbers in parsable
135.Pq exact
136values.
137.It Fl r
138Recursively display properties for any children.
139.It Fl s Ar source
140A comma-separated list of sources to display.
141Those properties coming from a source other than those in this list are ignored.
142Each source must be one of the following:
143.Sy local ,
144.Sy default ,
145.Sy inherited ,
146.Sy temporary ,
147.Sy received ,
148and
149.Sy none .
150The default value is all sources.
151.It Fl t Ar type
152A comma-separated list of types to display, where
153.Ar type
154is one of
155.Sy filesystem ,
156.Sy snapshot ,
157.Sy volume ,
158.Sy bookmark ,
159or
160.Sy all .

168Clears the specified property, causing it to be inherited from an ancestor,
169restored to default if no ancestor has the property set, or with the
170.Fl S
171option reverted to the received value if one exists.
172See
173.Xr zfsprops 8
174for a listing of default values, and details on which properties can be
175inherited.
176.Bl -tag -width "-r"
177.It Fl r
178Recursively inherit the given property for all children.
179.It Fl S
180Revert the property to the received value if one exists; otherwise operate as
181if the
182.Fl S
183option was not specified.
