GNOME Tweaks has a toggle to change the caps lock to ctrl:

enter image description here

How can I do either of the following via a bash script?

  • Toggle the setting so that I can see it enabled inside Tweaks
  • Just toggle the functionality (caps lock -> ctrl) itself, without changing the Tweaks setting

To enable: gsettings set org.gnome.desktop.input-sources xkb-options "['caps:ctrl_modifier']"

To disable: gsettings set org.gnome.desktop.input-sources xkb-options "[]"

EDIT: To address Don's comment below you can run gsettings get org.gnome.desktop.input-sources xkb-options to see if any other xkb-options are already set. If there are you can incorporate them too in the gsetting command, for example you might have gsettings set org.gnome.desktop.input-sources xkb-options "['altwin:menu', 'caps:ctrl_modifier']"

  • Note that while both your commands work fine, they will delete any other xkb options already present... see my post here... so scripting this via shell is not that simple. An easier way imo is via python's Gio.Settings – don_crissti Nov 28 '22 at 21:50
  • That's a fair point, @don_crissti. I've updated my answer to at least partially address this issue. – Anthony Kelly Nov 29 '22 at 09:47
