 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 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.


 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.


 EXAMPLES

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


 EXIT STATUS

The following exit values are returned:

0

Successful operation.


non-zero

An error has occurred.


 FILES

/proc/*

process files
