Bash script Onion start problem omega 2

[Christian Munk]

Re: python while problem

ahhh looks like i have to write my first bash script these days and also wanna include it with the start routine of the onion, but still have a problem....next one

here is the status:

...i can start the mp3 stream directly from the commandline with mpg123 http://.........mp3...stream => that works

1. here the full bash script i putted in /usr/bin folder

---

#!/bin/ash

    gpioctl dirin 0
    gpioctl dirin 1
    gpioctl dirin 2
    gpioctl dirin 3
    gpioctl dirin 6
    gpioctl dirin 7
    gpioctl dirin 8
    gpioctl dirin 9
     COUNTER=0
     while [  $COUNTER -lt 100 ]; do

BUTTON0=$(gpioctl get 0 | grep Pin | cut -b 10)
BUTTON1=$(gpioctl get 1 | grep Pin | cut -b 10)
BUTTON2=$(gpioctl get 2 | grep Pin | cut -b 10)
BUTTON3=$(gpioctl get 3 | grep Pin | cut -b 10)
BUTTON7=$(gpioctl get 7 | grep Pin | cut -b 10)
BUTTON8=$(gpioctl get 8 | grep Pin | cut -b 10)
BUTTON9=$(gpioctl get 9 | grep Pin | cut -b 10)
if [ $BUTTON0 = 'H' ]; then
killall mpg123
echo starting radio mode
echo GROOVE SALAD
mpg123 http://ice3.somafm.com/groovesalad-256-mp3 &
fi
if [ $BUTTON1 = 'H' ]; then
killall mpg123
echo starting radio mode
echo SECRETAGENT
mpg123 http://ice1.somafm.com/secretagent-128-mp3 &
fi
if [ $BUTTON2 = 'H' ]; then
killall mpg123
echo starting radio mode
echo OE1
mpg123 http://mp3stream3.apasf.apa.at:8000 &
fi
if [ $BUTTON3 = 'H' ]; then
killall mpg123
echo starting radio mode
echo GROOVESALAD
mpg123 http://ice3.somafm.com/groovesalad-256-mp3 &
fi
if [ $BUTTON9 = 'H' ]; then
killall mpg123
echo starting radio mode
echo SECRETAGENT
mpg123 http://ice1.somafm.com/secretagent-128-mp3 &
fi
if [ $BUTTON8 = 'H' ]; then
killall mpg123
echo starting radio mode
echo OE1
mpg123 http://mp3stream3.apasf.apa.at:8000 &
fi
sleep 1
done

2nd The script is called from the file /etc/rc.local, so it starts when the Omega2 reboots:

---

/usr/bin/radio.sh & > /dev/null
exit 0

---

3rd the hardware (buttons) seems fine to me working, but how can i try the script now and test it?

Make the script executable by running the command: " chmod +x radio.sh "

execute the script by typing " ./radio.sh "

i am not sure, how to test my skript? without including it immediately

i hope you can help me with my weired post

ps omega onion firemware is up to date. i also did "oupgrade -force" in the commandline

@Christian-Munk i certainly agree your post is a bit strange. are you asking forum members to debug, if necessary, and test your script? the formatting of the script in your post makes it hard for me to understand.

Hello, i put the bashscript in my dropbox. here is the link
https://www.dropbox.com/sh/u3s8lqdn0f9g6u2/AACvfddIZcKHp-cJ98nmrnCPa?dl=0[link text](link url)
maybe you can try to start it.

thx lg christian

@Christian-Munk the issue with me testing it is i need to have a working mpg123 client working on the omega2+ so i need to ask you how difficult is it to get that client operational on the omega2+ because i have never before used it, or even heard of it since i use youtube music to get my music feeds. is mpg123 a time consuming adventure?
thanks

[Christian Munk]

just type
run opkg update
opkg install mpg123
thats it.
to listen the stream i connected a small usb soundcard on my onion (with a powered usb adapter)

[Christian Munk]

@Douglas-Kryder and make sure you take the *.sh file from dropbox. It is my last upload and the streams should work

@Christian-Munk One little hint on avoiding some debugging....

if [ $BUTTON2 = 'H' ]; then

If the variable BUTTONn is null, you've got a problem. Wrap the variable and it's evaluation $ in double quotes so it at least evaluates to a null string, not a null.

if [ "$BUTTON2" = 'H' ]; then

take care!
Bill

@William-Scott

THX for the info

i included that, reduced the script to the only necessary stuff and put in the radioV2.sh in my dropbox.

https://www.dropbox.com/s/k73t8k848zceg5b/radioV2.sh?dl=0[link text](link url)

here is the error i get now on the last line:

/usr/bin/radioV2.sh: line 56: syntax error: unexpected "done" (expecting "then")

Any Ideas what is the problem here?

@Christian-Munk
In general, first thing I always recommend is changing
/usr/bin/radio.sh & > /dev/null
to
/usr/bin/radio.sh & > /var/log.radio.log
Why would you throw away whatever the author of a script was trying to tell you.

The technique to solve this and many problems in general is:

1. copy the origin source to source.broken (or similar)
2. remove a chunk of code, especially on of a group of similar segments.
3. Try it.
4. Save that version and go back to step 2 if it still fails.

I have found that having 2 windows open, one with vi chopping up the code and another executing the code allows you to undo the last delete +and examine it carefully.

Another thing that you can do, when if executes but not the way you want is the oldest(well second oldest after setting an address stop +from the front panel) add output statements like
echo "got to stage2" >> script.log
or
logger "stepping along count:$count:" #this goes to either the local syslog hopefully configured to save messages in /var/log or even +another system that can collect the messages if the target system cannot be accessed now (or later)

Get rid of most (not all ) of the if..fi . This won't fix the problem but will allow you to get a better view of what remains.
