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 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  member-
                     ships  in addition to parent-child relation-
                     ships. 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.
