Terminal parameters are stored as $LINES and $COLUMNS variables. Additionally you can use special term-operation programm, for example tput: tput lines # outputs the number of lines of the present terminal window. tput cols # outputs the number of columns of the present terminal window.


This command should give you the number of lines on the terminal: stty size | cut '-d ' -f1 Some systems might not implement stty size so you might need something like this instead: stty -a | tr \; \\012 | grep rows | tr -d ' rows'
