He had some utilities (that came with the compiler I thought, but I've
forgotten that detail to be honest). IIRC, he had a simple shell and the
traditional simple file manipulation, although again, IIRC he did not write
the associated tools, someone else had.

I wrote a lot of code in BDS C, remember it fondly (even though it's stdio
was non-stdio :)
I never heard about any Unix emulation from him, do you mean the libraries
or something else.
I ask because I wrote a bunch of tiny CP/M programms, in assembler because
I was using every trick I could to make them small. I believe the ones I
had on every floppy were:
ls
cp
mv
rm
and each one of those I made fit in either one or two 512 byte sectors
because they weren't memory resident, it had to spin up the floppy and
read them in each time I ran them. So I wanted them small for two
reasons: speed of reading them in and not taking up precious space on
the floppy.
I had a utils floppy that had larger programs on it, like grep, my quicknet
terminal emulator/file transfer tool (I wish I had saved the source to
that).
my CP/M machine was an Okidata with a color(!) monitor and a built in
printer with two floppies so I could do work on one floppy and get the
utils on the other. Hmm, wonder if there is picture of that machine
on the net? Of course there is:

So Clem, did Leor do any utilities that I didn't know about or are you
talking about his not so standard C library?
