However, if you use bash, it will set _shell_ variables, COLUMNS and
LINES, automatically. This isn't something that screen does, but bash.
Bash does _not_ export these by default, however; you'll need to do
$ export COLUMNS LINES
This may work, if the screen does not get resized while it is running.
I have my screen session inside an xterm, and resize frequently.
environment variables would still reflect the old value after a resize.
Rather unportably between Unixes:
eval $(resize)
resize requires having a terminal type that actually does xterm-style
answerback, which as at best a "maybe".
When run from within screen, we guarantee you that xterm-style
answerback is honored. Screen is an xterm-compatible device.
I used to use the eval $(resize) method a lot, but at some point, the
shell I use (bash 3.2.33, atm) has an option for checking the window
size before executing any command:
shopt -s checkwinsize
I'm not sure what version introduced this feature, I only discovered it
when I re-read the man-page after one of the 3.x releases.
