La commande 'proctree' est très utile pour lister une liste de processus attachés.
Par défaut, la commande vous liste le processus donné en argument ainsi que tous les sous-processus fils générés et les processus parents.
La syntaxe est décrite ci-dessous :
'proctree num_processus'.
L'option -a permet de détailler également les enfants du processus 0.
Ci-dessous la documentation AIX V6 officielle en anglais.

proctree Command
Purpose
Prints the process tree containing the specified process IDs or users.
Syntax
proctree [ -a ] [ { ProcessID | User } ]
proctree [ -a ] [ -T ] [ -t ] [ { -p ProcessID | -u User } ] [ -@ [ WparName] ]
Description
The /proc filesystem provides a mechanism to control processes. It also gives access to information about the current state of processes and threads, but in binary form. The proctools commands provide ascii reports based on some of the available information.
Most of the commands take a list of process IDs or /proc/ ProcessID strings as input. The shell expansion /proc/* can therefore be used to specify all processes in the system.
Each of the proctools commands gathers information from /proc for the specified processes and displays it to the user. The proctools commands like procrun and procstop start and stop a process using the /proc interface.
The information gathered by the commands from /proc is a snapshot of the current state of processes, and therefore can vary at any instant except for stopped processes.
The proctree command prints the process tree containing the specified process IDs or users. The child processes are 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 action is to report on all processes, except children of process 0.
When you specify the -@ flag with no parameters, all WPAR names are displayed. If you specify the WparName parameter, only those WPAR names are displayed.
For displaying thread IDs and associated pthread IDs, specify the -t option. For a kernel process, the proctree command only displays the thread ID.
