JLS(8) BSD System Manager's Manual JLS(8)
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.
