66Only some properties can be edited.
67See

69for more information on what properties can be set and acceptable
70values.
71Numeric values can be specified as exact values, or in a human-readable form
72with a suffix of
73.Sy B , K , M , G , T , P , E , Z
74.Po for bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, exabytes,
75or zettabytes, respectively
76.Pc .
77User properties can be set on snapshots.

93Displays properties for the given datasets.
94If no datasets are specified, then the command displays properties for all
95datasets on the system.
96For each property, the following columns are displayed:
97.Bl -tag -compact -offset 4n -width "property"
98.It Sy name
99Dataset name
100.It Sy property
101Property name
102.It Sy value
103Property value
104.It Sy source
105Property source
106.Sy local , default , inherited , temporary , received , No or Sy - Pq none .
107.El
108.Pp
109All columns are displayed by default, though this can be controlled by using the
110.Fl o
111option.
112This command takes a comma-separated list of properties as described in the
113.Sx Native Properties
114and
115.Sx User Properties
116sections of
117.Xr zfsprops 8 .
118.Pp
119The value
120.Sy all
121can be used to display all properties that apply to the given dataset's type
122.Pq Sy filesystem , volume , snapshot , No or Sy bookmark .
123.Bl -tag -width "-s source"
124.It Fl H
125Display output in a form more easily parsed by scripts.
126Any headers are omitted, and fields are explicitly separated by a single tab
127instead of an arbitrary amount of space.
128.It Fl d Ar depth
129Recursively display any children of the dataset, limiting the recursion to
130.Ar depth .
131A depth of
132.Sy 1
133will display only the dataset and its direct children.
134.It Fl o Ar field
135A comma-separated list of columns to display, defaults to
136.Sy name , Ns Sy property , Ns Sy value , Ns Sy source .
137.It Fl p
138Display numbers in parsable
139.Pq exact
140values.
141.It Fl r
142Recursively display properties for any children.
143.It Fl s Ar source
144A comma-separated list of sources to display.
145Those properties coming from a source other than those in this list are ignored.
146Each source must be one of the following:
147.Sy local , default , inherited , temporary , received , No or Sy none .
148The default value is all sources.
149.It Fl t Ar type
150A comma-separated list of types to display, where
151.Ar type
152is one of
153.Sy filesystem , snapshot , volume , bookmark , No or Sy all .
154.El

160.Xc
161Clears the specified property, causing it to be inherited from an ancestor,
162restored to default if no ancestor has the property set, or with the
163.Fl S
164option reverted to the received value if one exists.
165See
166.Xr zfsprops 8
167for a listing of default values, and details on which properties can be
168inherited.
169.Bl -tag -width "-r"
170.It Fl r
171Recursively inherit the given property for all children.
172.It Fl S
173Revert the property to the received value if one exists; otherwise operate as
174if the
175.Fl S
176option was not specified.
