I tried this in my bash here (under the "Terminal" program in Debian): larsi@marnie:~/src/emacs/trunk$ set | grep LINES LINES=24 larsi@marnie:~/src/emacs/trunk$ set | grep COLUMNS COLUMNS=80 So they're in my env at least. But I see I have this in my very ancient ~/.bashrc: # check the window size after each command and, if necessary, # update the values of LINES and COLUMNS. shopt -s checkwinsize -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
