# The BEACON_FILE holds the command for sending a beacon. So make this file part of the script.
# I shouldn't really do this, as it is a potential security risk. But the BEACON_FILE is as safe as this script itself.
# The BEACON_FILE can not be altered via the web interface, but only by the main program. So it should be ok.
# But this makes the code potential self altering, which is bad! Realy realy bad!
# But than again, is it really not the same as calling an external program from the script, as this program can also be alterred.
# Anyway, enough of my rambling, let's continue with the script.
# To be safe, lets do some minimal safety checks before executing the external file:
# BEACON_FILE should only have one line:
NR_OF_LINES=$(awk 'END { print NR }' $BEACON_FILE)
