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 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.
