I'm playing with unix v6 right now. I don't see the "man"
binary anywhere.. anyone know why?
I have v6 installed from tape. The tape has images for three
disks apparently, root, source and docs. The docs image has
a man directory with the man pages in them. I don't see a
man binary anywhere though, and I don't see the sources to
man in the sources directory either.
I checked the disk images available on the simh "kits" page.
It has man pages in /mnt/man but no sources or binary.
(by the way, this image is missing /usr/sys for some reason,
which is why I am running an installation from tape).
I also checked the
PDP-11/Trees/V6 directory on TUHS and similarly dont see
sources or binaries for man (though the man pages are present
in /usr/man).
There's even a /usr/man/man1/man.1, formatted online here:
http://wwwlehre.dhbw-stuttgart.de/~helbig/os/v6/doc/I/man.html
anyone know why the source and binary are missing from the
distributions?

The v6 man.1 manpage says "[man] is a shell command file",
so there is no source code, just the shell script.
Still, that doesn't explain why the script file missing.
It's not on the Dennis_v6 tape, nor the Ken_Wellsch_v6
tape in the archive. Intruiging!

I just booted up the interdata version and... it doesn't have 'man'
either...
I get the impression from /usr/doc/man that the man pages on the ID32 were
setup with a 'make' command to format and print them all....
I guess the man command didn't exist...????

Why is there a man page for it?
By the way, I found a /usr/bin/man command in
PDP-11/Distributions/other/Tim_Shoppa_v6
in the unix_v6.rl02 image. Oddly, it uses "cd" instead
of "chdir" and doesnt run in the normal v6 shell!
(cut and pasted in the attached file).
It also uses "set" which isnt supported in v6.
Although, it does look like a pre-v7 shell script
by the control flow constructs and lack of variables.
(compare to /bin/man in V7, which is a new style shell
script which wont run in V6).
There's also a /usr/ucb/man binary present. I haven't
tried it in stock v6.
Its pretty easy to boot the Tim_Shoppa_v6 image,
just un-gzip it and use:
set cpu 11/23
set tto 7b
attach rl0 unix_v6.rl02
boot rl0
in simh. At the boot prompt enter "unix".

That's very interesting indeed. FreeBSD has gone "back to the future"
here and replaced the man program that called groff, et al, with a
shell script. Given the complexity of the shell script, however, I
imagine it wouldn't work too well on v6. :)
