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.

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
