Maximize all windows from command line in linux (via wmctrl)

maximize_all.sh

#!/bin/bash
window_ids=$(wmctrl -l | cut -f1 -d " ")
for window_id in $window_ids
do
    wmctrl -i -r "$window_id" -b add,maximized_vert,maximized_horz
done

Thanks for sharing, I was struggling to know how to start each one of my startup applications maximized until I found wmctrl and then this script. Now, I will only have to start all the applications I need then run this handy script. 😊

very good! (y)

This is great!

I modified it slighty with

1. "toggle" instead of "add" I can switch back and forth
2. xargsso it could be one-line and then added as a bash alias.

wmctrl -l | awk '{print $1}' | xargs -n1  wmctrl -b toggle,maximized_vert,maximized_horz -i -r

if you want to avoid quotes you can replace the awk section with cut -d\ -f (not two spaces after the backslash)

....on second thought, I'm not sure "toggle" is ideal since it will un-maximize windows that are already maxed. might make two separate aliases instead.
