Well, no, that open does invoke a shell, albeit one with
no user input. It's still better to
pipe
fork
child exec explicitly
parent read pipe
Newer perl can actually use list form in the 'file'
section for open, so you'd be able to use that to
avoid a shell in the open without writing the code
yourself.
