NAME
     jls -- list jails

SYNOPSIS
     jls [-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:

     -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      Print a multiple-line summary per jail, with 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.
