title: Execute a terminal command from a Cocoa Desktop app
body: <p>I am trying to execute a command for creating a Cordova Project in my Cocoa Desktop App but It doesn't work.</p>
  
  <p>That's my code:</p>
  
  <pre><code>NSTask *task = [NSTask new];
      [task setLaunchPath:@"/Documents/Cordova/bin/ ./create ~/Documents/Cordova/HelloWorld2 org.apache.cordova.HelloWorld2 HelloWorld2"];
      [task setArguments:[NSArray arrayWithObjects:@"-l", @"-a", @"-t", nil]];
  
      NSPipe *pipe = [NSPipe pipe];
      [task setStandardOutput:pipe];
  
      [task launch];
  
      NSData *data = [[pipe fileHandleForReading] readDataToEndOfFile];
  
      [task waitUntilExit];
     // [task release];
  
      NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
      NSLog (@"got\n%@", string);
  </code></pre>
  
  <p>And that's output:</p>

  <p>I don't understand what is the problem? It can't find path for executing or can't execute?</p>
