On my home server sometimes I need to know what is happening. As the server does not have any monitor the only way how to get some kind of a response is using the embedded speaker.
Therefore I implemented a script which is accepting one parameter: the message. Message can be a label (uppercase) or a lower case text without punctuation. Predefined labels are:
- BOOTED
- SHUTDOWN
RESTARTCONNECTDISCONNECTFINISHEDERROR- and my favorite
STARWARS
And lower case text will be translated to Morse code.
Now if my server boots up STARWARS theme is played 😀
#!/bin/sh
modprobe pcspkr
function play() {
message=$1
if [[ $message == "STARWARS" ]]; then
