send notification email if process is not running

Question

I am using the following shellscript to check running process in a cron job:

ps -ef|grep myprocess|grep -v "grep"

I then need to send an email if the result is empty(meaning process is not running), how do I script this?

Answer 1

One solution:

pgrep processname &>/dev/null && exit 0
echo |mail -s"Aiie, process processname not running!" [email protected]

Then put it in a crontab like already suggested. Of course, it means you must have the mail command installed.

Answer 2

You can do it this way

PROCESS_FOUND=`ps -ef|grep myprocess|grep -v grep`
if [ "$PROCESS_FOUND" = "" ]
then
    #send mail from here ...Process not running
