Randall,
I kind of follow you here. Are you saying that I need to do both queries in each script to determine if the proper environment or variable parameters? What I was getting at is that I have used LINES & COLUMNS in scripts in the past that relied on both but didn't have to alter the environment. Why are these needed now?
I only meant to give you a data point per your request. The vq and eq procedures are generic and I use them quite a lot, though not that I can recall for COLUMNS. You can always just put an export command in your .bash_profile or .login file (I can never keep straight which you use for what but .bashrc will always work, of course, even though it's highly redundant to do so for environment variables). Anyway, I don't know if COLUMNS is updated when the terminal size is changed. I do know that the stty output is always current. I have another script for that, "tsize": -==--==--==--==--==--==--==--==--==--==--==--==--==--==--==- #!/bin/bash --norc rowsOnly= colsOnly= for arg; do case "$arg" in -r | --row | --rows) rowsOnly=1 colsOnly= ;; -c | --col | --cols) colsOnly=1 rowsOnly= ;; esac done stty -a \ |( if [ $rowsOnly ]; then sed -rn '/rows/ s/.*rows +([^;]+);.*/\1/p' elif [ $colsOnly ]; then sed -rn '/columns/ s/.*columns +([^;]+);.*/\1/p' else sed -rn '/rows.*columns/ s/.*(rows[^;]+;[^;]+);.*/\1/p' fi ) -==--==--==--==--==--==--==--==--==--==--==--==--==--==--==- % tsize rows 97; columns 180 It can easily be modified to output a COLUMNS (or ROWS) -setting command, of course.
