Cron scripts in /etc/cron.daily not running

If you put a script to be run by cron in cron.hourly, cron.daily, cron.weekly or cron.monthly but they won’t run, make sure that they:

• Are chmod +x
• Are owned by the correct user (like root:root)
• Start with #!/bin/sh or the corresponding shell used to execute them
• The filename doesn’t contain any dots, like a script name ending in .sh will not execute

You can also execute the command to verify that your script will be run:

run-parts –test /etc/cron.daily
