Hi all,

I need to write a script that will check what processes are currently running against a flat file containing a list of processes that should be running. For any process that is not running, I need to send an email.

The file list will be very basic:
proc1
proc2
proc3
proc4

What is the best way to do this? I thought about putting both sets of procs into an array and comparing them, but I quickly saw that was very, very illogical. Any hints as to how this could be done?

I'll write it, so I'm not asking for that, I just need to be pointed in the right direction.

try this :

for i in `cat /tmp/proglist.txt`
do
DUMMY=`ps -ef | grep $i | grep -v grep | wc -l`
if [ $DUMMY -gt 0 ]
then
echo "Process $i is running"
else
echo "Process $i is not running"
# mail to server
# I don´t not how to do this
# this is your part
fi
done

Thanks Fal5do, it's great help.

If you can, you could add a line to the beginning each of the procs

echo $$ >/u/procpid/proc1.pid (or some other safe place)

Then simplify the ps command to
ps -p`cat /u/procpid/proc1.pid`

since you already have the process id.
