Are there any command lines you can trace back to neither the UNIX shell or the various DOSes (or CP/M)?
The evolution of most command lines I know of go back to either the Bourne shell of the first UNIX machines (any of the *sh programs ultimately go back to sh, even csh/tcsh) or the CP/M command line (which the DOSes shamelessly ripped off and somewhat improved/extended). What I’m interested in is, essentially, an alternate route of evolution. Trouble is, I can’t think of any OSes that use a command line that can’t be described as either *nixes or DOSes.
Maybe the debug command line of the old MacOS is what I’m looking for, but I have no idea where to get information on it. I don’t even know if it fits my criteria.
So, anyone out there know of obscure CLIs? Do they even exist?
