ptree(1) ptree(1)
NAME
ptree - print process trees
SYNOPSIS
/usr/bin/ptree [-a] [-c] [-z zone] [pid | user] ...
ptree prints the process trees containing the specified pids or users, with child processes indented from their respective parent pro-
cesses. 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 pro-
cesses.
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.
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 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
The following exit values are returned:
0 Successful operation.
non-zero An error has occurred.
