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.

cron - daemon to execute scheduled commands (Vixie Cron)
SYNOPSIS
cron
DESCRIPTION
Cron should be started from /etc/rc or /etc/rc.local. It will return immediately, so you don't need to start it with '&'.
Cron searches /var/spool/cron for crontab files which are named after accounts in /etc/passwd; crontabs found are loaded into memory. Cron
also searches for /etc/crontab and the files in the /etc/cron.d/ directory, which are in a different format (see crontab(5)). Cron then
wakes up every minute, examining all stored crontabs, checking each command to see if it should be run in the current minute. When execut-
ing commands, any output is mailed to the owner of the crontab (or to the user named in the MAILTO environment variable in the crontab, if
such exists).
Additionally, cron checks each minute to see if its spool directory's modtime (or the modtime on /etc/crontab) has changed, and if it has,
cron will then examine the modtime on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab
file is modified. Note that the Crontab(1) command updates the modtime of the spool directory whenever it changes a crontab.
