Hi guys,

I am currently facing a problem with my current script, the script basically monitor a list of process on the Unix system. If a process is down it will send a notification e-mail to me.

Currently I am facing an error when running the script grep: RE error 41: No remembered search string, I never seen message before. I've checked Google and it state that you need to remove all grep -q, but I do not have grep -q in my script I only have grep.

Can anyone help me please about this message?

Thanks guys

Since you've posted no code there's no way to tell but psychic powers, but I'm guessing that it's complaining about not having a search string. It would be really nice to see the code.

Basically there are two funtion that I am using, this function will check for the current process.


checkProcess ()
{
PROCESS=$1
PROC_NOT_RUN=`$PS -ef | $GREP -i "$PROCESS" | $GREP -v "grep" | $WC -l` #determine how many times are the process is running
echo "Process Not Run $PROC_NOT_RUN"
return $PROC_NOT_RUN
}

This is my main funtion, I still not able to find out what was wrong, I have a feeling that when using grep and awk in one line it might cause the problem


$CAT $CONF_DEAMON | $AWK '{print $1}' | $GREP -v "^\#" | \
while read SERVICES
do
SERVICES_PATH=`$CAT $CONF_DEAMON | $GREP -v "^#[[:space:]]" | $GREP "^$SERVICES" | $AWK '{print $2}'`

# 1. Check for the process
checkProcess $SERVICES

if [ $? -eq $SUCCESS ]
then
echo $?
#addErrMSG "$SERVICES is currently not running please review the process under the path of $SERVICES_PATH"
#Send_Email

fi
done


Thanks for your help
