Top Forums UNIX for Dummies Questions & Answers Can cron be modified via a script? Post 302908661 by Corona688 on Wednesday 9th of July 2014 11:44:31 AM

The safest way is to have your script do it. [ -f /path/to/myscript-lock ] && exit 0

If you must edit cron automatically, I put a unique ID in the cron line to make it easy to match and difficult for a script to mistake.

Code:
0 * * * * /path/to/myscript.sh # 1234123132
