FORGET THE CRONTAB MAN 
For some reason many admins forget the field order of the
 crontab file and alway reference the man pages over-and-over.
 Make your life easy. Just put the field definitions in
 your crontab file and comment (#) the lines out so the
 crontab file ignores it.
 
 #minute (0-59),
 #|      hour (0-23),
 #|      |       day of the month (1-31),
 #|      |       |       month of the year (1-12),
 #|      |       |       |       day of the week (0-6 with 0=Sunday).
 #|      |       |       |       |       commands
 0       2       *       *       0,4     /etc/cron.d/logchecker
