[ Speculations whether YP has anything to with this, alluding to the

Yes it is significant that this "works" on Sun (actually SunOS 3.2 or
higher) and SystemV, but not on BSD-derived systems (other than Sun).
The reason? In SunOS 3.2 and higher /bin/sh is the SystemV.2 Bourne
shell.

On the Pyramid the trick works in the att universe but not in the
bsd universe.

The original poster of the question posted it from a Sun running SunOS 3.2
