Determine telnet window size.

[gawker]

I hope that this is the correct forum for this...

I'm writting a script that will list user data files in a directory. The script will allow the user to select the file using an associated number that is displayed next to the file name.

I want to control how many files (lines) are displayed based on the telnet window size (example: Using PCXware).

The smitty utility does the same sort of checking as you can't use smitty in a window that is less then 24 lines x 80 characters.

Is there a way to get the window dimensions?

Thank you.

stty size

Dunno how portable that is, its what i use along with linux, dont remember if its working on *bsd.

usually the $LINES and $COLUMNS env vars show the dimension, but they aint exported so not accessable by scripts or processes.. a short zsh/bash one line to bring them back looks like the following

size=( `stty size` ) LINES=$size COLUMNS=${size[1]}

. Mac for productivity
.. Linux for developement
... Windows for solitaire

Take a look at tput lines and tput cols
You may also already have environment variables like LINES and COLUMNS

Hope This Helps, PH.

Thank you xmb,

I found that "stty -a" gives me the environmental variables I need in one of the lines:

speed 9600 baud; 24 rows; 80 columns;

From which I can then control my data return.
