ptree(1)                         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 par‐
       ent  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     /usr/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
