Var log cron not updating

Because cronjobs are time based sometimes it is necessary to validate that the job ran at the scheduled time.

Sometimes people will configure a cron to send the output of the script to a user via system mail or redirect the output to a file; however not all crons are setup the same and many times they may be configured to send output to /dev/null hindering any ability to validate the job ran.

In this tutorial we will use the root account for simplicity.
