I've been trying to get less working on this system, which runs a/ux, and it seems to work just fine with one exception: when designated as PAGER, and called from man, less displays escape sequences as "^[<whatever>", so you end up with a lot of garbage on the screen, and no highlighting, underlining or whatever. I've installed less on several systems and have never seen this bizarre behavior before. Help! Thanks, bill

Edit the /usr/bin/man script so that it does mypager="$PAGER" rather than mypager="ul | $PAGER" and the escape sequence junk will go away. I'd also recommend using different LESS options under A/UX commandshell windows: in particular if you use scrolling rather than "clear screen" or "overwrite" then you will be able to scroll backwards through the manual page using the CommandShell scrollbars, rather than having to use less to do it. We are using less version 48, and define LESS=mqewh20. Personally I don't like the attempt to do bold headings and so I don't have PAGER defined, but it does work properly as described above. -- William Roberts ARPA: liam@cs.qmw.ac.uk Queen Mary & Westfield College UUCP: liam@qmw-cs.UUCP Mile End Road AppleLink: UK0087 LONDON, E1 4NS, UK Tel: 071-975 5250 (Fax: 081-980 6533)

Sigh. WHAT version of less, what are your compile options, what is the
setting of 'term' (e.g. ``$ echo $TERM'' to find out), etc etc
I've compiled the EXACT same version of less (ver.5) to run under all of SysV
on my 3B1 systems, HP-UX 3.* and 7.*, A/UX 2.0, etc. and it works PERFECTLY
with "man" as $PAGER on all of them. Note, though, I had to "fix" termcap and
terminfo under A/UX for proper VT100/VT200 support (since most my usage is
over the serial or net ports since I dislike the glare on the Apple monitors),
but no change was required to use the Mac's console.

I'd be interested in the termcap and terminfo fixes for proper VT100/VT200 support (could these make it into A/UX 2.0.1 please someone?). When you compiled less did you do it for "A/UX 2.0 as a SysV system" or "A/UX 2.0 as a BSD system" (or even "A/UX 2.0 as a POSIX system)? What A/UX specific #defines and libraries do you instinctively reach for when you first try compiling a new system? -- William Roberts ARPA: liam@cs.qmw.ac.uk Queen Mary & Westfield College UUCP: liam@qmw-cs.UUCP Mile End Road AppleLink: UK0087 LONDON, E1 4NS, UK Tel: 071-975 5250 (Fax: 081-980 6533)

I've installed less on several systems and >have never seen this bizarre behavior before. What you want to do is modify the /usr/bin/man script, the problem is that it calls /usr/bin/ul to do underlining before calling $PAGER, and this causes behavoir that is incompatible with less. Change the line that reads: mypager="ul | $PAGER" to mypager="$PAGER -s " -- Ron Flax ron@afsg.apple.com Apple Federal Systems Group
