Top Forums Shell Programming and Scripting A script that kills previous instances of itself upon running not killing child processes Post 302687549 by DeCoTwc on Thursday 16th of August 2012 08:15:21 PM

Either I'm not understanding your suggestion, or I'm not doing it properly.


Code:
[root@liwmgmt02 ~]# ps -ef|grep [n]ew.log
root     13507  7458  0 19:57 pts/1    00:00:00 bash ./new.logGen.sh
root     13514 13507  0 19:57 pts/1    00:00:00 bash ./new.logGen.sh
[root@liwmgmt02 ~]# kill -- 13507
[root@liwmgmt02 ~]# ps -ef|grep [n]ew.log
root     13514     1  0 19:57 pts/1    00:00:00 bash ./new.logGen.sh
[root@liwmgmt02 ~]#

Some one suggested to me using ps --ppid, and I came up with this:

Code:
ps --ppid $(cat /var/run/logGen.23223.pid)|while read -a i;do if [[ "${i[0]}" != PID ]];then kill "${i[0]}" > /dev/null;fi;done

though I'm not sure if this is what I'm going to go with. Just a thought for now.

kill(1) 						      General Commands Manual							   kill(1)

Name
       kill - send a signal to a process

Syntax
       kill [-sig] processid...
       kill -l

Description
       The command sends the TERM (terminate, 15) signal to the specified processes.  If a signal name or number preceded by `-' is given as first
       argument, that signal is sent instead of terminate.  For further information, see

       The terminate signal kills processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot  be  caught.
       By convention, if process number 0 is specified, all members in the process group (that is, processes resulting from the current login) are
       signaled.  This works only if you use and not if you use To kill a process it must either belong to you or you must be superuser.

       The process number of an asynchronous process started with `&' is reported by the shell.  Process numbers can also be  found  by  using	It
       allows job specifiers ``%...''  so process ID's are not as often used as arguments.  See for details.

Options
       -l   Lists  signal  names.  The signal names are listed by `kill -l', and are as given in /usr/include/signal.h, stripped of the common SIG
	    prefix.
