cron - clock daemon
Cron executes commands at specified dates and times according to the instructions in the
file /usr/lib/crontab. Since cron never exits, it should only be executed once. This is

Crontab consists of lines of six fields each. The fields are separated by spaces or tabs.
The first five are integer patterns to specify the minute (0-59), hour (0-23), day of the
month (1-31), month of the year (1-12), and day of the week (1-7 with 1=monday). Each of
these patterns may contain a number in the range above; two numbers separated by a minus
meaning a range inclusive; a list of numbers separated by commas meaning any of the num-
bers; or an asterisk meaning all legal values. The sixth field is a string that is exe-
cuted by the Shell at the specified times. A percent character in this field is trans-
lated to a new-line character. Only the first line (up to a % or end of line) of the com-
mand field is executed by the Shell. The other lines are made available to the command as
Crontab is examined by cron every minute.
