.Sh NAME
.Nm zfs-list
.Nd list properties of ZFS datasets
.Sh SYNOPSIS
.Nm zfs
.Cm list
.Op Fl r Ns | Ns Fl d Ar depth
.Op Fl Hp
.Op Fl j Op Ar --json-int
.Oo Fl o Ar property Ns Oo , Ns Ar property Oc Ns … Oc
.Oo Fl s Ar property Oc Ns …
.Oo Fl S Ar property Oc Ns …
.Oo Fl t Ar type Ns Oo , Ns Ar type Oc Ns … Oc
.Oo Ar filesystem Ns | Ns Ar volume Ns | Ns Ar snapshot Oc Ns …
.
.Sh DESCRIPTION
If specified, you can list property information by the absolute pathname or the
relative pathname.
By default, all file systems and volumes are displayed.
Snapshots are displayed if the
.Sy listsnapshots
pool property is
.Sy on
.Po the default is
.Sy off
.Pc ,
or if the
.Fl t Sy snapshot
or
.Fl t Sy all
options are specified.
The following fields are displayed:
.Sy name , Sy used , Sy available , Sy referenced , Sy mountpoint .
.Bl -tag -width "-H"
.It Fl H
Used for scripting mode.
Do not print headers and separate fields by a single tab instead of arbitrary
white space.
.It Fl j , -json Op Ar --json-int
Print the output in JSON format.
Specify
.Sy --json-int
to print the numbers in integer format instead of strings in JSON output.
.It Fl d Ar depth
Recursively display any children of the dataset, limiting the recursion to
.Ar depth .
A
.Ar depth
of
.Sy 1
will display only the dataset and its direct children.
.It Fl o Ar property
A comma-separated list of properties to display.
The property must be:
.Bl -bullet -compact
.It
One of the properties described in the
.Sx Native Properties
section of
.Xr zfsprops 7
.It
A user property
.It
The value
.Sy name
to display the dataset name
.It
The value
.Sy space
to display space usage properties on file systems and volumes.
This is a shortcut for specifying
.Fl o Ns \ \& Ns Sy name , Ns Sy avail , Ns Sy used , Ns Sy usedsnap , Ns
.Sy usedds , Ns Sy usedrefreserv , Ns Sy usedchild
.Fl t Sy filesystem , Ns Sy volume .
.El
.It Fl p
Display numbers in parsable
.Pq exact
values.
.It Fl r
Recursively display any children of the dataset on the command line.
.It Fl s Ar property
A property for sorting the output by column in ascending order based on the
value of the property.
The property must be one of the properties described in the
.Sx Properties
section of
.Xr zfsprops 7
or the value
.Sy name
to sort by the dataset name.
Multiple properties can be specified at one time using multiple
.Fl s
property options.
Multiple
.Fl s
options are evaluated from left to right in decreasing order of importance.
The following is a list of sorting criteria:
.Bl -bullet -compact
.It
Numeric types sort in numeric order.
.It
String types sort in alphabetical order.
.It
Types inappropriate for a row sort that row to the literal bottom, regardless of
the specified ordering.
.El
.Pp
If no sorting options are specified the existing behavior of
.Nm zfs Cm list
is preserved.
.It Fl S Ar property
Same as
.Fl s ,
but sorts by property in descending order.
.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 .
For example, specifying
.Fl t Sy snapshot
displays only snapshots.
.Sy fs ,
.Sy snap ,
or
.Sy vol
can be used as aliases for
.Sy filesystem ,
.Sy snapshot ,
or
.Sy volume .
.El
.
.Sh EXAMPLES
.\" These are, respectively, examples 5 from zfs.8
.\" Make sure to update them bidirectionally
.Ss Example 1 : No Listing ZFS Datasets
The following command lists all active file systems and volumes in the system.
Snapshots are displayed if
.Sy listsnaps Ns = Ns Sy on .
The default is
.Sy off .
See
.Xr zpoolprops 7
for more information on pool properties.
