how to call this .sh script in my C cgi script?

[nickyeng]

Hi all,

i have this problem.
i dont know how to call my .sh script from my C cgi script.

the sound chosen by user will be dynamically echoed, if user wanted to. Else send the original sound to user.

here is my code:

 if(cgiGetValue("version") == "dynamic" ) {
      // call addecho.sh here with the WAV filename "train.wav"
       // output the result returned by addecho.sh to form a valid http response.
} else {
     // output the original sound file to user.
}
 

here is my addecho.sh code:

#!/bin/bash
TEMP=`mktemp`
#sox "../$1" -t wav "${TEMP}" chorus 0.6 0.9 50.0 0.4 0.25 2.0 -t 60.0 0.32 0.4 1.3 -s 
sox "../$1" -t wav "${TEMP}" echo 1.0 1.0 150.0 0.9 300 0.6 450 0.3
cat ${TEMP}
rm -f ${TEMP}
 

my lec say addecho.sh take the filename of a WAV file as its argument. It modifies the WAV to simulate the echo of a tunnel and outputs the resulting sound on standard out.

please help me out with the comment line above that i didn't know what to code.
