Heh. Don't forget your own attempts to use a shredder as a PRNG stream.
Shell redirections can be complicated, so this topic is going to
come up once in a while. The example in the shred info page is fairly
unintuitive, so it deserves a bit of explanation. I imagine most readers
who saw it simply accepted it as written, which is why the bug went
undiscovered for two decades.
