Get screen height, width from shell

Is there a way to get the screen height and width from the shell? I don’t want the terminal size, but the actual size of the display screen.

Hi
xrandr should provide the info you need.

For anyone that would like to find the terminal window size, which can also be important can use these commands:

  WIDTH=`tput cols`
  HEIGHT=`tput lines`

I have been using the following command to center text in some script files:

col_os=$((( $WIDTH - 80) / 2 ))

80 was the width in characters I wanted to center on the screen.

Thank You,

xdpyinfo also works even if there is no randr support.

xdpyinfo | grep dimension

And to find out DPI from xdpyinfo. This one I learnt from @malcolmlewis:

xdpyinfo | grep resol

It was also pointed out to me that you can use the following terminal/bash command format to find the terminal width and height as well:

WIDTH=$(tput cols)
HEIGHT=$(tput lines)

The Terminal Center Command for 80 Characters might best be done this way in the event that the present terminal width is 80 or less characters.

if  $(WIDTH) -le  80  ] ; then
  col_os=0
else
  col_os=$((($WIDTH - 80) / 2 ))
fi

Thank You,
