 +Just download the code, and compile it with gcc:
 +
 +<​code>​
 +gcc trayopen.c -o trayopen
 +</​code>​
 +
 +Then, running it, it will return a 0 if it's open, or a 1 if it's closed.

 +Here's a sample bash script to call it:
 +
 +<​code>​
 +#!/bin/bash
 +trayopen /dev/dvd
 +if [[ $? -eq 0 ]]; then
 +  echo "Open for business!"​
 +elif [[ $? -eq 1 ]]; then
 +  echo "​Sorry,​ already occupied."​
 +fi
 </​code>​ </​code>​
