PTREE(1) User Commands PTREE(1)

NAME

ptree - print process trees

SYNOPSIS

/usr/bin/ptree [-a] [-c] [-g] [-w] [-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(5). This option implies the -a
option.

-g
Use line drawing characters. If the current locale is a UTF-8
locale, the UTF-8 line drawing characters are used, otherwise
ASCII line drawing characters are used.

-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(5).

-w
Allow output lines to wrap. Normally output lines are
truncated to the current width of the terminal window.

-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

Example 2:

The following example prints the process tree (including children of
process 0) for processes which match the command name ssh with ASCII line
drawing characters:

$ ptree -ag `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.

process files
