       ptree - print process trees

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

       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.

       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 rela-
		  tionships. See process(4). This option implies the -a option.

       -z zone	  Zones.  Print  only processes in the specified zone. Each zone ID can be speci-
		  fied 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  pro-
       cesses 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

       See attributes(5) for descriptions of the following attributes:

       |Availability		     |SUNWesu			   |
       |Interface Stability	     |See below.		   |

       The human readable output is Unstable. The options are Evolving.
