[comp.os.minix] teaching os/job control

PCF1%VAXA.YORK.AC.UK@cunyvm.cuny.edu (06/09/89)

Once upon a time I read on a news group (maybe this one) words to the
effect that "With no sign of GNU appearing in the near future people appear
to be trying to make Minix into a PD UNIX". This is an admirable aim, but
should be kept totally separate from the Teaching OS version. I can think of
one site that went to great pains to try and PREVENT its students acquiring
ST-MINIX, aparrently because it did not want them knowing too much about how
UNIX worked since this was thought to be a security risk !! Whilst this may
seem like extreme paranoia I would not like to see it spreading to other
sites if teaching Minix tends towards full UNIX.

However, there is a great need for a PD version of UNIX and if such a system
could be built around Minix as-is whilst keeping the original as the teaching
system then we would all benifit. I use ST-Minix on my own machine and recently
had the misfortune to come across "proper" System-V on a 68000 box. It was
soooo-slow. People complain about the speed of Minix but it goes like the
wind compared to "proper" UNIX on small systems.

As for job control, I am one of these people who

i) Dislikes csh intensely
ii) Dislikes windows intensely

About a year ago I was working on a Uniplus+ system which had a program on it
called "shl". I have never come across this before, but its function was to
allow mulitiple shells to be run, switching between them by using Z to exit
from a running "sh" back to "shl" and then specifying the shell to be resumed.
(shells could have names assigned to them). This was the best way I have found
of running more than one job at once. MOst screen-based programs will redraw
quite happily if you type Z into them.

Has anyone else come across this, and if so what about a version for Minix ?
Better than csh any day I think.....
