Hi ,
My problem is that I am not able to list all process id of any process.
Quote:
[root@server public_html]# pstree -p | grep httpd
|-httpd(17888)-+-httpd(9134)
| |-httpd(9136)-+-{httpd}(9140)
| | |-{httpd}(9141)
| | |-{httpd}(9142)
| | |-{httpd}(9143)
| | |-{httpd}(9144)
| | `-{httpd}(9145)
| `-httpd(12594)-+-{httpd}(12596)
| |-{httpd}(12597)
| |-{httpd}(12598)
| |-{httpd}(12599)
| |-{httpd}(12600)
| `-{httpd}(12601)
If you see pstree command it shows many process id under https. But if I run ps command its not listing all the process id for httpd.

It is just listing the PPID and immediate child process id only. I want to have all child process id.
Why pstree and ps command output is different.
Can someone point me in the right direction so that I can get all the child process id using other command rather than using pstree command.
Thank you

I have managed to write one line script to get the list all process id of HTTPD including PPID TGID and PID

Listing all child pid and deleting it in reverse order
