How do I find the width & height of a terminal window?

Question

As a simple example, I want to write a CLI script which can print = across the entire width of the terminal window.

#!/usr/bin/env php


        

Answer 1

Inspired by @pixelbeat's answer, here's a horizontal bar brought to existence by tput, slight misuse of printf padding/filling and tr

printf "%0$(tput cols)d" 0|tr '0' '='

Answer 2

And there's stty, from coreutils

$ stty size
60 120 # <= sample output

It will print the number of rows and columns, or height and width, respectively.

Then you can use either cut or awk to extract the part you want.

That's stty size | cut -d" " -f1 for the height/lines and stty size | cut -d" " -f2 for the width/columns

Answer 3

• tput cols tells you the number of columns.
• tput lines tells you the number of rows.
