User Commands ptree(1)
NAME
ptree - print process trees
SYNOPSIS
/usr/bin/ptree [-a] [-c] [-z zone] [pid | user] ...
DESCRIPTION
The ptree utility prints the process trees containing the
specified pids or users, with child processes indented from
their respective parent processes. An argument of all digits
is taken to be a process-ID, otherwise it is assumed to be a
user login name. The default is all processes.
OPTIONS
The following options are supported:
-a All. Print all processes, including children
of process 0.
-c Contracts. Print process contract member-
ships in addition to parent-child relation-
ships. See process(4). This option implies
the -a option.
-z zone Zones. Print only processes in the specified
zone. Each zone ID can be specified as
either a zone name or a numerical zone ID.
This option is only useful when executed in
the global zone.
OPERANDS
The following operands are supported:
pid Process-id or a list of process-ids. ptree
also accepts /proc/nnn as a process-id, so
the shell expansion /proc/* can be used to
specify all processes in the system.
user Username or list of usernames. Processes
whose effective user IDs match those given
are displayed.
