[TUHS] Other Bell Labs shells from the 80s?

[TUHS] Other Bell Labs shells from the 80s?

[Arnold Robbins via TUHS]

Hello all.

The CL memo was interesting, in a way.  The notations are clearly
much more verbose than the standard shell, and I found that a little
off-putting.

The memo's references refer to Marc Rochkind's 2dsh --- Marc, whatever
happened to that? Are source and or the memo for it available somewhere?

Also it refers to a shell by Blewett and arder called Parser. Anyone
have that memo?

Just wondering,

Thanks,

Arnold

Much to the credit of Multics innovation, brought to you by Ken's

Hello,

I just noticed this is the first post I've ever seen from this list. Thank you so much to the person that added me. I hope everybody has a good day today. I really love Unix.

It took me a while to figure out the references...

Which was that the command interpreter was "just" a user level
program that could be replaced.

The weeks when his wife was on vacation and he turned his
filesystem into an OS.

Did I get them right?

Thanks,
