Bug/misfeature in 4bsd /bin/sh

[David Steffens]

In article <117 at sickkids.UUCP> mark at sickkids.UUCP (Mark Bartelt) says:

In article <474 at auspex.UUCP> guy at auspex.UUCP (Guy Harris) says:

Guy is correct -- an (almost) plain vanilla v7 /bin/sh gives:
	1 1 2 1 2 1

The system I used for testing is known as "v7m", an early release
of DEC's Ultrix-11.  The code is basically Bell v7 re-worked
to run on a non-splt I/D PDP11.  The /bin/sh binary is dated
5 May 1979 and derives from sources dated 12 Jan 1979.
