Re: ksh script question

I like to use a marker file.  It works great if you have a job that takes longer to run than its frequency interval :) 
 
# Begin Script
semfn=/tmp/`basename $0`.${sid}.RUNNING    # Semaphore Filename, Are we running already?
if [ -f $semfn ]
then
        echo "%-Warn, $0 is Already Running, to continue: rm $semfn"
        return 1
fi
touch $semfn                             
 
# ... Processing stuff
 

rm $semfn               # We are done, so delete semaphore
# End Script

If I have a script scheduled via cron how do I check to see if it is already running and therefore not run it a second time?
 
TIA, Mark
