Linux – How to automate window tiling with a custom width? (Cinnamon)

I got the answer here.

this would be the script to maximize it to the right half of the screen:

#!/bin/bash
# resizes the window to full height and 50% width and moves into upper right corner

#define the height in px of the top system-bar:
TOPMARGIN=27

#sum in px of all horizontal borders:
RIGHTMARGIN=10

# get width of screen and height of screen
SCREEN_WIDTH=$(xwininfo -root | awk '$1=="Width:" {print $2}')
SCREEN_HEIGHT=$(xwininfo -root | awk '$1=="Height:" {print $2}')

# new width and height
W=$(( $SCREEN_WIDTH / 2 - $RIGHTMARGIN ))
H=$(( $SCREEN_HEIGHT - 2 * $TOPMARGIN ))

# X, change to move left or right:

# moving to the right half of the screen:
X=$(( $SCREEN_WIDTH / 2 ))
# moving to the left:
#X=0; 

Y=$TOPMARGIN

wmctrl -r :ACTIVE: -b remove,maximized_vert,maximized_horz && wmctrl -r :ACTIVE: -e 0,$X,$Y,$W,$H

To move to the left, just change the X-Line to X=0. (If you use Ubuntu Unity, you need to adapt RIGHTMARGIN too I use RIGHTMARGIN=102)

defining the right margins this solves the bug, that the second time you call it, it moved to the very top of the screen, ignoring the top-toolbar.

Sure, just set your window focus mode to "mouse". Go into cinnamon settings => Windows and then:

That will cause the window under the mouse to have focus without raising that window. If you want to write on your terminal, place the mouse over it and you can do so without raising it.

Personally, I also disable raise-on-click so that I need to click on the title bar or Alt+click to raise a window but that's just me.
