Top Forums UNIX for Dummies Questions & Answers how to cancel a cronjob if the cronjob still running Post 302446201 by rajamadhavan on Wednesday 18th of August 2010 04:06:29 AM

Hi,
One way I can think of is to put a check on the script that runs as a part of crontab. Whatever you want to do with the script you do after a check that if any command of similar name is still running. example: lets say if you are running /home/user/script.sh every one minute, then add a check
Code:
ps -ef | grep "script.sh" | grep -v grep

on your script.sh in the beginning
