starting up radio and one led

Question

I'm using this in as my /etc/init.d/pirateRadio.sh

the Radio does play a wav with this in the rc.local

export PATH=/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/sbin:/usr/bin
sleep 10
(
 exec &>> /var/log/my_rc_local.log
 cd /home/pi/pifm/pifm && ./pifm left_right.wav 100.1 stereo
) &

I had the led working before I added the above by itself in the rc.local

# Light ON AIR LED
sudo python /home/pi/pifm/pifm/ledon.py &

but now I am trying to combine both, in a shell and i am lost. I usually get [src/libout123/wav.c:755] error: flushing failed: Broken pipe

This is what I have craeted for pirateRadio.sh

#!/bin/bash
# /etc/init.d/pirateRadio.sh
### BEGIN INIT INFO

export PATH=/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/sbin:/usr/bin
sleep 20

# This works in the rc.local

case "$1" in
    start)
        echo "StARRRRRRRting Pirate Radio"
        sudo /usr/bin/mpg123 -4 -s -Z /home/pi/Music/* | cd /home/pifm/pifm/ && sudo ./pifm - 100.1
        ;;
    stop)
        echo "Stopping Pirate Radio"
        killall pifm
        ;;
    *)
        echo "Usage: /etc/init.d/pirateRadio.sh start|stop"
        exit 1
        ;;
esac

# Light ON AIR LED
sudo python /home/pi/pifm/pifm/ledon.py &

exit 0

Oh and additionally, if I correct, "esac" to "case" I get

sudo ./pirateRadio.sh start
./pirateRadio.sh: line 37: syntax error near unexpected token `newline'
./pirateRadio.sh: line 37: `case '

Answer 1

You are piping the output of mpg123 into cd. This won't work as intended. cd before the pipeline, or simply use an absolute path to your pifm script.

If you absolutely have to cd and want to have your main script stay in the same directory, open a sub-shell with parantheses ( commands … ).

Oh, and additionally, you don't correct esac to case. That's reversed intentionally, it's the end of case, just as fi is the end of if. Oddly do/done do not follow this convention.
