Most of this is from: https://linux.m2osw.com/transform-gnome-settings-command-lines

You can list all settings using:

# export your current settings to a file
gsettings list-recursively > a.txt
# change the settings you want using the GUI then re-export and diff

Change the settings you want to script using the settings GUI then re-export:

gsettings list-recursively > b.txt

You can then diff:

diff a.txt b.txt

Set a setting using gsettings set (eg. workspaces settings I use):

gsettings set org.gnome.mutter dynamic-workspaces false
gsettings set org.gnome.desktop.wm.preferences num-workspaces 5
gsettings set org.gnome.mutter workspaces-only-on-primary false

For extension activation/deactivation use:

gnome-extensions enable '[email protected]' # allow setting monitor brightness, quite awesome
gnome-extensions disable '[email protected]'

(bonus) removing dash-to-dock shortcuts

I map those keys to go to workspace 1-5, and those shortcuts are not configurable in gnome keyboard settings GUI. Some Gnome spin of force the extension so you might need to remove those shortcuts:

for e in {1..10}; do
  gsettings set org.gnome.shell.extensions.dash-to-dock "app-ctrl-hotkey-$e" \[\]
  gsettings set org.gnome.shell.extensions.dash-to-dock "app-shift-hotkey-$e" \[\]
  gsettings set org.gnome.shell.extensions.dash-to-dock "app-hotkey-$e" \[\]
done
