I find that anything I have to do twice winds up in a shell script, on the assumption that
I’ll do it again. So I’ve written a lot of scripts lately, mostly to automate some tools
to run our software validation system. These aren’t long (10-15 lines) and I freely give
them to others knowing that they will either ignore it (mostly) or use it as is without
ever looking at the internals.
I think that editor scripts have died out. ed is almost designed for scripting, and with
vi, emacs, and other GUI based editors the concept of scripting the editor has died away.
Sad, I do remember writing some really hairy ed scripts.
A quick read of Hank Levy’s book (thanks for the link) brings back (somewhat bad) memories
of working on the iAPX 432. I found the chip interesting in concept, and poorly suited for
what the company wanted done. Trying to fold the software to fit the hardware didn’t work
out. The project was abandonded.

That's an interesting topic, but it also gets my mind thinking about UNIX features
that were wonderful but didn't evolve as computers did.
My two examples of this are editor scripts and shell scripts. In the day, I would write
at least one shell script and several editor scripts a day. Most of them were 2-4 lines
long and used once. But they allowed operations to be done on multiple files quite
quickly and safely.
With the advent of glass teletypes, shell scripts simply evaporated -- there was no
equivalent. (yes, there were programs like sed, but it wasn't the same...).
Changing, e.g., a function name oin 10 files got a lot more tedious.
With the advent of drag and drop and visual interfaces, shell scripts evaporated as well.
Once again, doing something on 10 files got harder than before. I still use a lot of
shell scripts, but mostly don't write them from scratch any more.
What abstraction mechanisms might we add back to Unix to fill these gaps?

OK, I guess I'll be the one to start things going on the COFF list.
What other features, ideas etc. were available in other operating
systems which Unix should have picked up but didn't?
[ Yes, I know, it's on-topic for TUHS but I doubt it will be for long! ]
