NAME
jls - list jails
SYNOPSIS
jls [--libxo] [-dhNnqsv] [-j jail] [parameter ...]
DESCRIPTION
The jls utility lists all active jails, or the specified jail. Each jail
is represented by one row which contains space-separated values of the
listed parameters, including the pseudo-parameter all which will show all
available jail parameters. A list of available parameters can be
retrieved via "sysctl -d security.jail.param". See jail(8) for a
description of some core parameters.
If no parameters or any of the options -hns are given, the following four
columns will be printed: jail identifier (jid), IP address (ip4.addr),
hostname (host.hostname), and path (path).
The following options are available:
--libxo
Generate output via libxo(3) in a selection of different human
and machine readable formats. See xo_parse_args(3) for details
on command line arguments.
-d List dying as well as active jails.
-h Print a header line containing the parameters listed. If no
parameters are given on the command line, all is assumed.
-N In the standard display mode, print each jail's name instead of
its numeric ID. If the jail does not have a name, the numeric ID
is printed instead.
-n Print parameters in "name=value" format, where each parameter is
preceded by its name. If no parameters are given on the command
line, all is assumed.
-q Put quotes around parameters if they contain spaces or quotes, or
are the empty string.
-s Print parameters suitable for passing to jail(8), skipping read-
only and unused parameters. Implies -nq.
-v Extend the standard display with a multiple-line summary per
jail, containing the following parameters: jail identifier (jid),
hostname (host.hostname), path (path), jail name (name), jail
state (dying), cpuset ID (cpuset), IP address(es) (ip4.addr and
ip6.addr).
-j jail
The jid or name of the jail to list. Without this option, all
active jails will be listed.
