RE:'less' can't determine terminal size?
Dear Sirs, I think that this bug is related to the one I reported on 2002/11/25 RXVT geometry bug.

Hi, Sergei, :)
Thank you for the speedy response!

This is interesting, since the size of the window (as shown when I
turn on line numbers ('-N') in 'less') is actually *25* lines high
(columns are correct at 80).
After resizing the rxvt window to increase the number of lines by 1,
'stty -a' correctly shows that there are 26 rows. Weird!
Thanks for any ideas,

Subject: 'less' can't determine terminal size?
Hi, All, :)
I updated my installation recently, and I'm now suffering from an odd
problem with less. I hope that somebody can point me in a direction for
my own investigations. I had been running 1.3.12, I believe - after the
refresh on Friday my cygwin1.dll is at 1.3.15. bash is 2.05b.0(7). I
run bash via rxvt-2.7.2-14. Here's my rxvt run command:
C:\WINNT\system32\cmd.exe /c start C:\cygwin\bin\rxvt.exe -tn rxvt -fg
grey -bg black -fn Fixedsys -sr -sl 5000 -e /bin/bash --login -i
I believe these environment variables are relevant:
TERM=rxvt
LESS=iFMSX# 8
CYGWIN=tty nontsec
My problem is this: 'less' no longer properly updates the screen when I
scroll through a file. Paging forward is fine, but when trying to
scroll by line ('j' or 'e'), 'less' tells me that it is moving through
the file, but the display doesn't update. The status line (which '-M'
enables) shows the currently displayed lines changing ('75-97', '76-98',
77-99', etc.), but the displayed data doesn't change. Paging forward
again causes the screen to update properly.
Also, when I scroll backward ('k'), the normally-blank command line
(bottom
line) becomes filled with the previous status line. So, if I'm at the
bottom of the file and the bottom two lines are:
=
.bash_profile lines 105-127/127 (END)
=
Then, after pressing 'k', the bottom two lines will read:
=
.bash_profile lines 104-126/127 99%
.bash_profile lines 105-127/127 (END)
=
This *seems* to mean to me that 'less' can't determine the right size my
rxvt window. My theory is reinforced because 'less' suddenly finds its
brains again when I resize the window manually.
How should I go about fixing this? Thanks in advance for any pointers,
---Jason Tiller

In my fiddling, I tried adding '-geometry 80x25' to my rxvt
invocation just to see what would happen. Strangest thing - my window
size was *26* lines. When I set -geometry to 80x24, rxvt opened up
a *25* line window.
Any idea why this might be happening? In all cases, if I manually
resize the window, this seems to sync things up and everything's
kosher after that.
Thanks for your help,

RE: 'less' can't determine terminal size?
Looks like rxvt bug. Did you try xterm instead?

I don't know if I'd be so quick to implicate rxvt - it could just as
easily be my setup. I would hardly describe myself as sophisticated
in these terminal issues - heck, most of the Unix tty model is beyond
me.
Setting '-tn' in the rxvt invocation to xterm (as opposed to rxvt)
made no difference that I could detect.
Perhaps it is a bug, but I'd like to more digging, if you or someone
else could point me at things to target.
Thanks,
