NAME

       ptree - print process trees

SYNOPSIS

       /usr/bin/ptree [-a] [-c] [-z zone] [pid | user] ...

       ptree  prints  the  process  trees  containing the specified pids or users, with child processes indented from their respective parent pro-
       cesses. 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  pro-
       cesses.

       The following options are supported:

       -a	       All. Print all processes, including children of process 0.

       -c	       Contracts.  Print  process  contract  memberships  in  addition to parent-child relationships. 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.

       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.

       Example 1: Using ptree

       The following example prints the process tree (including children of process 0) for processes which match the command name ssh:

       $ ptree -a `pgrep ssh`
	       1     /sbin/init
		 100909 /usr/lib/ssh/sshd
		   569150 /usr/lib/ssh/sshd
		     569157 /usr/lib/ssh/sshd
		       569159 -ksh
			 569171 bash
			   569173 /bin/ksh
			     569193 bash

       The following exit values are returned:

       0	       Successful operation.

       non-zero        An error has occurred.

       /proc/*	       process files
