| Quote (roberts @ Oct. 08 2007,11:04) | As shown in the perl script, /usr/local/bin/MyCron uses a slightly enhanced crontab
| Code Sample | ############################################################################
# This script reads /etc/crontab one line at a time and executes commands
# in a manner similar to the real cron. Crontab entries are seven space
# separated fields. The first 6 fields are the time stuff (slightly
# enhanced) and the remainder of the line is considered the command and
# will be passed to the system (almost) as is for execution.
# Crontab fields: MM HH DD MO WD YY <command>
# EG: "32-46 15 12 5 * 2006 cmd" (3:32pm to 3:46pm 12 May 2006)
# "10 8-17 * 5 * cmd" (8:10am - 5:10pm everyday in May)
# "0 0/2 * * 6 cmd" (every two hours, on the hour, on Saturday) ############################################################################

Ok,thanks for that, I should have seen that when I was looking at the script while I was getting errors.
Correct me if I'm wrong, but it appears that the second and third examples in the text from the script that you posted only contain 5 fields before the command. If this is allowed, why would my old crontab with 5 fields throw an error until I entered the 6th field?
Thanks again for your help
