Where, exactly, is /dev/null? I imagine it as a sort of void, a black hole of the system to which I can banish things, send thoughts into exile. I sent all my mail to /dev/null, this afternoon, due to a forgotten then. You see, if you write a mail filter that says that if such and such save /dev/null and forget the then that should come in between, well, you’re actually going to save every piece of mail you receive to /dev/null. Which is a term so poetic that I completely refuse to look it up and discover its true meaning. Devices, null, nothing, I’m sure I’m close enough.
I found it useful but disconcerting that even though it took me hours to realise that I’d made a mistake (0 emails in five hours is abnormal, it’s obvious) the email was resurrected. I caught the truant then, hammered it into place (with some assistence, I gratefully admit) and checked my mail. And it all arrived.
So where was that mail? Did it come back from /dev/null? Or did it never go there? Surely by rights something once banished should never return?
