Hello world!
This is my first posting, so I hope that everything is ok.
While doing the Minix upgrade from 1.3 to 1.5.10,
I found there is no man command, with a proper database as under UNIX.
For this reason I wrote a shellscript which works as follows:
There should be a /usr/man and a /usr/catman directory, each with the
man[1-9] subdirectories. If no chapter is given when called, my man
looks at first for a catman/man1 entry. If this fails, the man/man1
directory will be used and the page would be nroffed before output etc...
For getting the catman/man[1-9] entries, I wrote a little c program
which converts the MINIX-man files into "proper" man files. The files
will still have to be placed into the correct directories, but what's
a shell for, anyway!?!
The advantage of my shellscript over the MINIX-man command is that
you can easily extend the manuals for local programs. If Andy can't post
the nroff sources, his formatted pages will be in catman, but any other
author should publish nroff texts. MINIX-man needs the "al"-capability,
but my vt101 misses something like that. Each manual will be accessible
with this command. Ok, this is what I am talking about:
---- snip here ---- or cut ----- killing to this line would be ok too ----
cd /usr
N=nroff
s=1
for i
do case $i in
[1-9]*) s=$i;;
-t) N=troff;;
-n) N=nroff;;
-*) echo Unknown option \"$i\";;
*) if test -f catman/man$s/$i.$s
then cat catman/man$s/$i.$s
else
if test -f man/man$s/$i.$s
then ${N} -man man/man$s/$i.$s
else
found=no
for j in 1 2 3 4 5 6 7 8 9
do
if test -f catman/man$j/$i.$j
then found=yes; cat catman/man$j/$i.$j
else
if test -f man/man$j/$i.$j
then
found=yes
${N} -man man/man$j/$i.$j
fi
fi
done
case $found in
no) echo $i: no manual page found
