Of old shells and pipe symbols

[Andrew Klossner]

[]

	"Before the Bourne shell there was the Mashey shell.  It
	supported ^ for the pipe symbol not |.  This was a very
	primitive shell ... For example wild card were expanded in a
	separate process, yuck."

It sounds like the /bin/sh distributed with Unix v6, but that shell
accepted both '^' and '|'.  In the early 1970s, terminals on which it
was easy to key '|' were not widespread.  The classic terminal, the
TTY33, had no way to key '|', '{', '}', '~', or '`'.  (Or lower case
letters, for that matter.)
