Note Submitter: nemo ---- On the off chance you always get the same return value (in my case 11, although it may differ) when you call <code>passthru</code>, or <code>exec</code>, you may want to investigate the possibility that the desired command is segfaulting during the <code>exec</code>. <p>Writing text out at the very start does not always work: the pipes aren't always emptied. <p> If you want to know about a few return values, check out the man page for <code>sh</code>.
