Well, Dave Korn of Bell Labs decided that the C shell wasn't the only shell
worth developing; the "Korn shell" is a shell compatible with the Bourne
shell, but with a history and aliasing mechanism (the aliasing mechanism
has both short C-shell style aliases and full-blown builtin shell scripts,
which can have multiple lines and loops and everything) and job control
(as well as arithmetic and arrays). I've not used it - there don't seem to
be may copies outside the Labs - but a talk was given at the last USENIX on
it and it looks like a winner. So call up Larry Isley at Western's licensing
group in Greensboro, NC, and pester him unmercifully until Western gets its
act together and licenses it - in source form, please, not all of us are
running 5.0 on a PDP-11, VAX-11, or 3B.
