How can I resize the current window using a keybind?

I am using Xubuntu desktop, I want to use a keybind (application shortcuts in settings) to activate a command to resize the current window to a predetermined size.

For example: wmctrl -r Firefox -e 1,-1,-1,1000,600resizes any an active firefox window to 1000x600.

The problem is it only works for Firefox, I want to do it to the currently active window (by which I mean the window that has focus).

I know xdotool getwindowfocus getwindowname gives me the current window

but wmctrl -r xdotool getwindowfocus getwindowname -e 1,-1,-1,1000,600 does nothing.

Is there anyway to do this? My guess is maybe I have to use a pipe but I'm not sure.

Code (from posts #6 and #8 in Use wmctrl to unmaximize a window - not toggle:

#!/bin/sh
wmctrl -r :ACTIVE: -b remove,maximized_vert
wmctrl -r :ACTIVE: -b remove,maximized_horz
wmctrl -r :ACTIVE: -e 1,510,21,510,700

The first two wmctrl lines are needed for use on active windows which are maximized.

You can choose values for the third line according to your needs.

• Save the code as resize.sh in ~/bin.
• Open ~/bin in Thunar, the file manager, and change the properties of resize.sh by ticking Allow this file to run as a program.
• Add the bin folder to $PATH using sudo -H mousepad /etc/environment to insert /home/your_login_name/bin: at the beginning of $PATH.
• My path is this: PATH="/home/dkbose/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games" where dkbose is my user name (aka login name) which you should change to yours. Note the : which is used after each path except the last one and the presence of double quotes.
• Running . /etc/environment made the change take effect immediately.
• You can assign an available keyboard shortcut of your choice to run resize.sh.
