I have problem with a csh script. This script simply search for a certail process id and kill that using simple kill -5 <pid>. Everything is okay untill there is valid process id trapped. But if the process id is already cleaned before the execution of the kill command, but script ends saying the pid not found.
Is there any mechanism, I can apply to force the script not to exit from the shell and keep in loop for the next one even the process id is not found ?
It can be done, but requires more details. If the PID is not found, you said "loop for the next one" which next one? Are you giving it a list of PID's to be killed or continue checking for the same PID?
if ($chk < $fmin || $chk > $fmax) then
echo "OUT OF RANGE. Current $chk%. Normal from $fmin% to $fmax%" >> $MLOG
if ("$bchk" == "0") then # If backup is not running, force a sync
# Following line is added by sraj as often the BEGBLOCK process found uncleaned normally
set procid=`lgdump -b | head -3 | tail -1 | nawk -F. '{print $(NF-1)}' | sed '1,$s/ //g'`
if ("$procid" !="") then
kill -5 $procid
endif
sleep 5
fmdmn -F 'file.db'
sleep 3
fmdmn -F 'file.db'
echo " -> Action taken was: force database synch. " >> $MLOG
endif
endif
Okay, those "lgdump", "fmdmn" commands are the database utilities. So don't be confused. Even if the process is cleaned from OS part still its been shown alive by "lgdump" utility which I want to trap here. But the script exits when the "kill -5" do not find any such process. I just want to restrict my script from quiting in this case.
Please see if can be of some help.
Regards...

Hi everyone,
I am trying to configure AIX 6.1 using syslogd to send syslog event to syslog server configured on RHEL. However, RHEL never receives the events.
