Lisp shells

John Lacey requested information on Lisp shells. John Ellis implemented
a shell for a PDP-11/45 running Unix in Harvard Lisp in 1979.

John Levine has a paper about using Lisp for a command language in the
same issue of SIGPLAN Notices ("Why a Lisp-Based Command Language?").

Of course, you might do well to look into the Lisp Machine interface, both
before and after the fancy Symbolics interface that allowed non-Lisp-syntax
commands. Any you might consider gnu-emacs plus all the extensions (like
monkey mode) to be a fairly reasonable shell, with lisp as an extension
language.
