RE: Cron - Any advanced options?

I use a lock file for this purpose...something like this


#Check if the file exits at the start


if [ -e $FILE1 ]
        echo 'Already running -This one aborted!'
touch $FILE1
chmod 666 $FILE1


do the do here with appropriate waits


sleep 1
rm $FILE1
exit code stuff here

Your mileage may vary,  etc.....
