While I'm at it: quick debug of a crontab entry:
Example:
it is Friday as 22:00pm exactly so set your job for 2 minutes in the future:
create your job with crontab like:
Code:
2 22 * * *  /home/cmccabe/test.sh

wait 3 minutes, check your expected output - email or whatever.
Remove the test cron entry. Wash, rinse, repeat until you have your code working AND you have it running as expected.

Also note the "6" you have in your original entry will be different in different locales. Some places the week starts with Monday, other days, Sunday. So I cannot tell what day you are looking at.

Also check out anacron - allows you to turn off the machine and have jobs run anyway, later at the first chance.

kep_reload

KEP_RELOAD(1)						      General Commands Manual						     KEP_RELOAD(1)

NAME

       kep_reload - Update Predict's Keplerian elements

SYNOPSIS

	kep_reload

DESCRIPTION

       KEP_RELOAD is a simple utility that forces an immediate reload of PREDICT's Keplerian database through a socket connection while PREDICT is
       running in server mode.	It is especially useful in environments where PREDICT runs continuously, and periodic  Keplerian  element  updates
       are made outside of PREDICT, such as through scripts run through a crontab.

       The  "kepupdate"  script  found	in this directory is an example of a Keplerian element update script that can be run on an automated basis
       through a crontab.  It is designed to be placed in your home directory under a subdirectory  called  "cronjobs".   It  downloads  Keplerian
       orbital	data  from  www.celestrak.com  using  the  HTTP  protocol.   (The  "wget" utility, available from the Free Software Foundation, is
       required, and is included in many Linux distrubutions.)

       Type crontab -e to edit your crontab.  Simply add the following entry:

	       0 8 * * * kepupdate

       and your orbital database will update each morning at 8:00 AM (provided you have a network connection at that time).

       See the crontab man page for more information on editing your crontab.
