Just thought I'd add to what Don Cragun said. Your OS version may be deeply tied to script you are attempting to run. A few *nix version have csh as a default shell. Most these days will not even have csh installed by default. Or it may be installed somewhere other than /bin/csh, like /usr/bin/csh. You might want to run a `which csh` to ensure its installed and the correct path is being used.

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.
