I am trying to run a program which checks to see if a process is running. If the process is not running, I want to start (re-start) the process. If the process is still (already) running, do nothing.

Here is the process; it starts manually:
$java Validation


here is my code to see if it is still running:
logfile1=/usr/test/file1.log
logfile2=/usr/test/file2.log

if ( ps -ef | grep Validation )
then
date>>$logfile1
echo val program already running>>$logfile1
else
date>$logfile2
echo val program needs restarting>>$logfile2
/usr/test/java Validation>>$logfile2
fi


PROBLEM:
When the Validation program stops (I stopped it manually), and the above code runs, it still thinks the process is running.
When I type "ps -ef | grep Validation" at the command line, it returns:
grep Validation

This is nothing more than the command I just entered. I guess this is why the above code still thinks my java program is running, but it is not.

When I execute "ps -ef | grep Validation" from the command line when the Validation program is running, I get:
/usr/test/java Validation
grep Validation

Why I am getting "grep Validation" returned?
How can I stop from getting "grep Validation" returned?

Thank you so much!
