Is anyone else upset with the way man works with multi-listing man pages?
For example, "man mount" gives you the printing for all listings of "mount",
but it always scrolls/clear the last page of a section before you have a
chance to read it and then starts up with the 1st page of the next listing.
For example, assume that mount has 3 listings: the 1st has 5 pages, the 2nd
2 and the 3rd 4. When "man mount" is done, it'll show pages 1-4 (pausing
at each screenfull), but then it show page 5, then immediately clear and show
page 1 of listing 2.
This is because more always exits at EOF, instead of waiting for you to
tell it to exit (ala less and pg). Hence, when the last page is shown, more
exits as soon as it "types" it, the eval in man (/usr/bin/man is a shell
script) exits and then the next listing is piped to more which immdiately
clears the screen and shows the next listing.
Changing the filter used by man (either by PAGER or editing /usr/bin/man) is
no help because:
1) less can't handle the "escape sequences" for bold, etc.
2) pg don't work right with "man -Tlp stuff | lpr"... you
get the stupid escape sequences written out on the hardcopy.
I guess pg don't look at -T

(Geez, some people just don't think :):):) 'Course, that's the way Apple distributed it ;) Once I added "export TERM" right above the "now print out pages" line in /usr/bin/man, pg works fine!

The /usr/bin/man script has been bugging me a lot too until tonight when I read the postings about it. I tried Jim's suggestion and it still did not work for me (perhaps I didn't do it right, perhaps my version of less affected things a little. Anyway, I did get it work, however, by changing the following line: ---------- if [ "$PAGER" = "" ] then mypager="more -s" else # Pages such as pg need to have ul handle underlining, but less # does not. You may want to reflect this difference in your PAGER # enviroment variable (e.g. setenv PAGER "ul | pg" or # setenv PAGER "less -s"). # mypager="ul | $PAGER" # use for pg mypager="$PAGER" # use for less fi ---------- The original version of man just had the line: mypager="ul | $PAGER" (along with a slightly different comment above it). This may work fine for the pg command, but ul in front of my less gave me a lot of garbage, so I made the change above and it seems to work great. I didn't even have to export the TERM variable as Jim suggested. I am running A/UX V2.0 in case it matters.

For example, -Tlp prints out some garbage when using pg (don't know about less, have to try it out) and piping the output to lpr. As I understand it, eval spawns a shell to run it's argument. Although TERM in defined in man, it's not exported to the eval shell, although the TERM of the main process (ie. me, when calling man) is exported (as things are set up on my Mac)... so the pager sees MY TERM, and not man's, unless TERM is exported to pager. At least, I think so ;) -- ======================================================================= #include <std/disclaimer.h> =:^) Jim Jagielski NASA/GSFC, Code 711.1 jim@jagubox.gsfc.nasa.gov Greenbelt, MD 20771 "Kilimanjaro is a pretty tricky climb.
