some sed and grep games to extract screen dimensions

screen-dimensions.sh

#!/bin/sh

screen_dim=$(xdpyinfo | grep dimension | awk '{print $2}')
echo "screen size is $screen_dim"
screen_dim_x=$(echo ${screen_dim} | sed -e 's/x/\n/g' | sed -n '1p' )
screen_dim_y=$(echo ${screen_dim} | sed -e 's/x/\n/g' | sed -n '2p' )
echo "screen width is $screen_dim_x"
echo "screen height is $screen_dim_y"

exit 0
