  • Why not? ps auxf|grep hlds_run should show you the processes you are looking for.

Try perl, the Swiss Army Chainsaw. Here's me finding the PID that holds port 80 open, then listing all the children:

[me@lory ~]$ sudo netstat -apn|grep -w 80|grep LISTEN
tcp        0      0 :::80                       :::*                        LISTEN      8308/httpd          
[me@lory ~]$ ps -ef|perl -n -e  '@j=split /  */; print "@j" if ( @j[2]==8308) ; '
apache 9235 8308 0 Dec05 ? 00:01:49 /usr/sbin/httpd
apache 10040 8308 0 Dec08 ? 00:00:41 /usr/sbin/httpd
apache 10477 8308 0 Dec07 ? 00:01:13 /usr/sbin/httpd
apache 10478 8308 0 Dec07 ? 00:01:21 /usr/sbin/httpd
apache 10658 8308 0 Dec08 ? 00:00:29 /usr/sbin/httpd
apache 10662 8308 0 Dec08 ? 00:00:26 /usr/sbin/httpd
apache 10666 8308 0 Dec08 ? 00:00:28 /usr/sbin/httpd
apache 10668 8308 0 Dec08 ? 00:00:35 /usr/sbin/httpd
apache 12694 8308 0 Dec06 ? 00:01:39 /usr/sbin/httpd
apache 12695 8308 0 Dec06 ? 00:01:43 /usr/sbin/httpd
apache 12696 8308 0 Dec06 ? 00:01:39 /usr/sbin/httpd
apache 18671 8308 0 08:41 ? 00:00:18 /usr/sbin/httpd
apache 21585 8308 0 Dec08 ? 00:00:42 /usr/sbin/httpd
apache 22010 8308 0 Dec05 ? 00:01:33 /usr/sbin/httpd
apache 22011 8308 0 Dec05 ? 00:01:49 /usr/sbin/httpd
apache 22012 8308 0 Dec05 ? 00:01:36 /usr/sbin/httpd

If you only want the PIDs:

[me@lory ~]$ ps -ef|perl -n -e  '@j=split /  */; print "@j[1]\n" if ( @j[2]==8308) ; '
9235
10040
10477
10478
10658
10662
10666
10668
12694
12695
12696
18671

You can use pkill (man) to kill all processes by name.

  • I run multiple servers if i use pkill - he killing all processes with name is added after command. I need solution to find another process id by concrete process.

  • You can use the -u option to only kill processes by a certain user.

  • Try this ps -ef | grep <unique string you want gone> | cut -b9-14 | xargs kill -9

  • Not work correctly. And maybe is better to know pids of another process by port of (Chief pid) Here is example: if i have server with udp port 27015 (hlds_linux + hlds_run + hlds_run) i need to check hlds_linux(27015) to find pid's of second two hlds_run

use ps auxf like i told in my previous comment, you can see an output as follow
