CRON JOBS (crontab) TIPS & TRICKS
The syntax and examples for scheduling cron jobs in UNIX/Linux.

crontab filename
    Where filename is the properly formatted text file ( see example below ) containing the list of jobs you'd like the the computer to run for you at the scheulded times.
crontab -l
    List the the cron jobs the computer currently has scheduled for you and what filename was used to create them. If no cron jobs have been setup, yet, you'll see something like "no crontab for username". Where username is the user you are currently logged in as.
Example crontab file:
    # The following is the proper format for a crontab file.
    # min hour day month dow (day of the week) command
    # valid dow values are 0-6 where 0=Sunday
    # 1 1 * * * /full/path/to/command
    # Uncommenting the above would run once a day at 01:01 am
    # */5 * * * * /full/path/to/command
    # Uncommenting the above would run every 5 minutes.
    # However, this will only work on newer vresions of crontab.
    # Older versions would require uncommenting the line below.
    # 0,5,10,15,20,25,30,35,40,45,50,55 * * * * /full/path/to/command
