correct.  Doug's original proposal was very nonlinear.  Ken's genius was finding an implementable and useful subset.

you’d do `..’ thinking it’s the same as `cd ..’, except it’s actually `cd /bin/..’.

I just found

                http://wryun.github.io/es-shell/

 

I’ve never actually used es, this or any other version; this is the first I’ve heard you

couldn’t just use the original.

 

Hey, does anybody know if Tom Duff really invented process substitution? ( <{} )

There’s a comment in ‘A Retrospective’ (1978, I think - it’s in the 1978 BSTJ edition

`UNIX Time-Sharing System’; I have a tenth-anniversary reprint called ‘UNIX System

Readings And Applications’) by Dennis Ritchie about how a syntax for non-linear

pipelines has already been proposed. /dev/fd wouldn’t have existed yet, so does

anybody know what he’s referring to here?

 

Whoever it was, I bet it was Doug.
