У меня получилось))

function setupAndLaunch(sh_name:String):void
{
	var shFilePath:String= File.documentsDirectory.resolvePath(sh_name+'.sh').nativePath;
	var cmdFile:File=new File('/bin/bash');
    var processArgs:Vector.<String>= new Vector.<String>;
    processArgs.push('-c');         
    processArgs.push('bash '+sh_name);
    var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
    nativeProcessStartupInfo.arguments = processArgs;
    nativeProcessStartupInfo.executable = cmdFile;
    nativeProcessStartupInfo.workingDirectory = File.documentsDirectory;
 
    process = new NativeProcess();
    process.start(nativeProcessStartupInfo);
}

Дело в том что Shell Script запускается из AS3 не напрямую, а через bash.
