Raspberry Service designen

Am Beispiel von WPA-Ping (wird von mir NICHT genutzt)

Das Script sieht so aus:

echo >> /usr/local/bin/wpaping << "EOFWPA"
#!/bin/bash
#
# Loop forever doing wpa_cli SCAN commands
#

sleeptime=120  # number of seconds to sleep. 2 minutes (120 seconds) is a good value

while [ 1 ];
do
    wpa_cli -i wlan0 scan
    sleep $sleeptime
done

EOFWPA

Der Service selber wird so gestaltet:

echo >> /lib/systemd/system/wpaping.service << "EOFWPA"
