 PTREE 1 "Sep 3, 2019"
 NAME
ptree - print process trees
 SYNOPSIS
/usr/bin/ptree [-a] [-c] [-s svc] [-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 and their associated SMF FMRIs,
in addition to parent-child relationships. See process(4).
This option implies the -a option.


-s svc

Print only processes with an SMF service FMRI matching the argument. The FMRI
may be in truncated form (such as 'console-login'). This includes child
processes even if they are not members of the service contract.
See process(4).


-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
