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 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. AUTHOR

crontab - maintain crontab files for individual users (ISC Cron V4.1) SYNOPSIS
crontab [-u user] file crontab [-u user] [-l | -r | -e] DESCRIPTION
Crontab is the program used to install, deinstall or list the tables used to drive the cron(8) daemon in ISC Cron. Each user can have their own crontab, and though these are files in /var, they are not intended to be edited directly. If the cron.allow file exists, then you must be listed therein in order to be allowed to use this command. If the cron.allow file does not exist but the cron.deny file does exist, then you must not be listed in the cron.deny file in order to use this command. If neither of these files exists, only the super user will be allowed to use this command. If the -u option is given, it specifies the name of the user whose crontab is to be tweaked. If this option is not given, crontab examines "your" crontab, i.e., the crontab of the person executing the command. Note that su(8) can confuse crontab and that if you are running inside of su(8) you should always use the -u option for safety's sake. The first form of this command is used to install a new crontab from some named file or standard input if the pseudo-filename ``-'' is given. The -l option causes the current crontab to be displayed on standard output. The -r option causes the current crontab to be removed. The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables. After you exit from the editor, the modified crontab will be installed automatically. SEE ALSO
crontab(5), cron(8) FILES
/etc/cron.allow /etc/cron.deny STANDARDS
The crontab command conforms to IEEE Std1003.2-1992 (``POSIX''). This new command syntax differs from previous versions of Vixie Cron, as well as from the classic SVR3 syntax. DIAGNOSTICS
A fairly informative usage message appears if you run it with a bad command line. AUTHOR
