Editing the crontab
Will ask you what editor you want to use
Next is to add your cron job to the file
The cron job runs in a certain format of minute (0-59), hour (0-23, 0 = midnight), day (1-31), month (1-12), weekday (0-6, 0 = Sunday), command
As an example
The script will run at 5:30AM everyday
A cron job can be user-defined as long as the name is added to the cron job
At 3:45 pm everyday user roderick will run a script.
