Locally, I can use the mouse to resize a window, and the $COLUMNS and
$LINES variables are automatically filled in.
On many remote xterm sessions, they aren't.
Does anyone have any idea where to start figuring out what is wrong, and
what I can do to correct it?
LINES and COLUMNS are legacy mechanisms which may serve as a workaround
if the system doesn't otherwise handle screen size changes properly.
They should not be needed on modern systems where the tty driver
maintains the information.
(You may note that mintty has not set them initially but they get set on
resize - by whatever means... - while in a cygwin console they are not
used at all.)
So if you happen to have these variables set on a system which does not
maintain them, they don't get changed on resize and confuse your
environment. In most cases the best remedy is to just unset them - does
that help?
