i have a bash script called from a cron job. i want to change the terminal size so, within the script, i tried: stty cols 160 rows 60 the result of the script indicated that there is a standard io error when this line is run from the cron job. it works fine when run from an xterm shell however. how can i tell the kernel the size of the io device from a cron job? whatever the default value is when the cron job is run is too small for my needs.
