Command to display current terminal window's settings?


Hell All,

I was wondering if there is a command line command that will display the current terminal's settings?

For example I would like to run the command and it will display the current window's settings, in order to view for instance the window's geometry size?


Thanks in Advance,
Matt

Hey Allen, thanks for the reply.

I tried the command and this was the output:
Code:
# xrandr
xrandr: Failed to get size of gamma for output default

   320x200       119.0  
   320x175       120.0
Not sure what all that is?

I came across this command below which does display the correct stuff, but I have to click the window that I want to display the data for.
Code:
# xwininfo

xwininfo: Please select the window about which you
          would like information by clicking the
          mouse in that window.

xwininfo: Window id: 0x1e04618 "mmartin@mmartin.paoli.jwpepper.local:/"

  Absolute upper-left X:  359
  Absolute upper-left Y:  161
  Relative upper-left X:  0
  Relative upper-left Y:  0
  Width: 1081
  Height: 705
  Depth: 32
  Visual: 0x74
  Visual Class: TrueColor
  Border width: 0
  Class: InputOutput
  Colormap: 0x1e00003 (not installed)
  Bit Gravity State: NorthWestGravity
  Window Gravity State: NorthWestGravity
  Backing Store State: NotUseful
  Save Under State: no
  Map State: IsViewable
  Override Redirect State: no
  Corners:  +359+161  -240+161  -240-184  +359-184
  -geometry 133x40+357+132
By default, when you run the command the mouse then turns into a "plus" looking sign, and it tells you to select the window that you want to display.

There are 2 options that are to use a "name" or "id" instead of using the mouse. Do you know if there is a default "name" or "id" for the current window I am in? Or is there a way to get either of those? I ask because my goal is to do this programmatically, without any human interaction (so no one will be able to use the mouse to select the window).


Thanks,
Matt

Ok so I think I found a way to do this.

If I do the following I can get the "Active" window's id.

Code:
 # xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)"
_NET_ACTIVE_WINDOW(WINDOW): window id # 0x1e04618
So that current window's id is "0x1e04618".

Thanks,
Matt

Nice catch:
Code:
xwininfo -id $(xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)" | cut -d " " -f5) | grep "geometry" | cut -d " " -f4
seems to isolate what you want.

Hey Allen, thanks for your help.

This is my solution below. The result is to isolate the windows geometry so I can check and make sure it is a certain size.
Below shows how I get the "Active Window's Geometry" so I can use it later in a script.

Here's what I got:
Code:
#!/bin/bash

#Finds and Sets the "Active" Window's ID to variable "WINDOW_ID"
WINDOW_ID=$(xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)"| cut -d ' ' -f 5)

#Uses the $WINDOW_ID variable to get the window's full geometry setting.
FULL_GEOMETRY=$(xwininfo -id "$WINDOW_ID" | grep "geometry" | cut -d ' ' -f 4)

#Separate the geometry to have only the "rows x cols"
ACTUAL_GEOMETRY=$(echo $FULL_GEOMETRY | cut -d '+' -f 1)

echo $ACTUAL_GEOMETRY



________OUTPUT________

167x35
