ptree(1) User Commands ptree(1)NAMEptree - 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 addi‐
tion 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 effec‐
tive 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
