That works for

/tmp/>echo "hello world\n" | myscript

and now called on its own doesn't hang

/tmp/>myscript

but there again its not clear how a usage message could be printed out.

But it now fails when passed a filename

/tmp/>cat x

/tmp/myscript x

it doesn't print the contents of the file :-( Isn't there a simpler solution? I thought that this would have a simple, forehead slapping, solution.
