Is there any keyboard-shortcut or trick to center all open windows?

Hello!
I am looking for a keyboard-shortcut or trick to center all open windows at once on the active screen??
The reason is if I switch off external screen with higher resolution, the windows from this screen are mostly 'offscreen' .

Try this script. Make it executable and attach it to a keyboard shortcut. It requires both the wmctrl and xdotool packages.

#!/bin/sh

# get the current desktop
CURR_DESK=$(wmctrl -d | grep "*" | awk '{print $1}')

# get the screen dimensions
IFS='x' read screenWidth screenHeight < <(xdpyinfo | grep dimensions | grep -o '[0-9x]*' | head -n1)

# for every window on this desktop
for w in $(wmctrl -l | grep " $CURR_DESK " | awk '{print $1}')
do
    # raise the window
    wmctrl -ia $w

    # center the window
    width=$(xdotool getactivewindow getwindowgeometry --shell | head -4 | tail -1 | sed 's/[^0-9]*//')
    height=$(xdotool getactivewindow getwindowgeometry --shell | head -5 | tail -1 | sed 's/[^0-9]*//')
    newPosX=$((screenWidth/2-width/2))
    newPosY=$((screenHeight/2-height/2))
    xdotool getactivewindow windowmove "$newPosX" "$newPosY"

done

Note: it will also raise and center minimized windows - not sure if this is what you want - it can be modified to check for those as well.

thanks for the script

i get an error when I try to run it

./centerWindows.sh: 7: Syntax error: redirection unexpected

any ideas?

oh, I'm running xfce in termux proot-distro.
i have xdotool and wmctrl installed and working fine

thanks

Interesting. The script still works for me.

Try this version instead:

#!/usr/bin/env bash

WIDTH=1920
HEIGHT=1080

while read ID X Y W H
do
	NX=$(($WIDTH/2-$W/2))
	NY=$(($HEIGHT/2-$H/2))
	wmctrl -i -r $ID -e 0,$NX,$NY,$W,$H
done < <(wmctrl -lG | grep -v " -1 " | awk '{print $1" " $3" "$4" "$5" " $6}')

exit 0

It only uses wmctrl and takes the screen dimensions manually.

Make sure you edit the WIDTH and HEIGHT variables to match your current screen dimensions.

Glad it helped.

Most of my scripts have been posted here in the forum. Just search for "bin/bash" or "bin/sh" or "usr/bin/env" and user "Toz" to get a result set.
