I have a script that runs a series of scripts numbered 001,002,003,004... etc down to 041 right now, will be more in the future - and these scripts them selves use some cursor control to print a progress bar and other status information and get the width and height of the terminal from tput cols and tput lines respectively.

Without rewriting the sub-scripts, I would like to reserve one line at the bottom for overall status information for the outer script. I was curious if there was a way to set what tput replies for lines and cols.

There must be a way because tmux achieves it. I was thinking there may be an environmental variable but the only change I can see that tmux makes when running env is setting the $TERM to screen.

Any help would be greatly appreciated

WRT tmux, the stuff in that is running inside tmux, which provides multiple shells and windows. Ie, it is not doing this via shell commands. So going that route means writing a pretty serious application. – goldilocks Dec 19 '12 at 19:27
Well it has to be altering something tput is reading, I tried looking up the source of tput but didn't understand it at all – donatJ Dec 19 '12 at 20:36

The following will let you customize the number of lines and cols tput returns

export LINES=1000
export COLUMNS=1000
