• Linux: recursively delete empty directories

  Solution

  # Print empty directories:
  find . -type d -empty -print
  # Delete empty directories:
  find . -type d -empty -delete

• Linux: toggle display on or off

  Solution

  Replace DP-4, 1920x1080 & 144.0 with your displays information

  xrandr --listactivemonitors | grep DP-4; if [ $? -ne 0 ]; then xrandr --output DP-4 --mode 1920x1080 --rate 144.0; else xrandr --output DP-4 --off; fi

  For scale, the font sizing of Gnome Tweaks seems to do a better trick than xrandr --scale.
