Hi
does anyone know of the equivalent of "ptree <PID>" command which can be used on IBM (AIX) machine. I was trying to use "ptref" but it produces too many lines of "unrelated " to the PID output.
May be someone has this issue before. Thanks a lot -A (2 Replies)
Hi,
Recently did a ptree on a vsh PID and found that the only child process underneath the vsh parent is rlogin (telnet session(s)). Is there any way to drill down further from here? What causes rlogin to make vsh go high or is it rlogin? The cpu utilization at times is at 48-49%. We want to... (0 Replies)
Hello guys,
Is there any command to check the all child processes of a process like `ptree`?
ptree is not working in Linux..

Unix (and Linux) uses a process tree that gives a natural security, by simple inheritance of attributes.
The following ptree script shows it. It runs on all Linux flavors.
Mostly useful for debugging.
#!/bin/sh
# Solaris style ptree
&& exec /usr/bin/ptree "$@"

ptree
ptree(1)ptree(1)NAME
ptree - print process trees
SYNOPSIS
/usr/bin/ptree [-a] [-c] [-z zone] [pid | user] ...
ptree prints the process trees containing the specified pids or users, with child processes indented from their respective parent pro-
cesses. 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 pro-
cesses.
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.
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.
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
The following exit values are returned:
0 Successful operation.
non-zero An error has occurred.
/proc/* process files
