In my ~/.bashrc

Terminal() {
    TerminalDarkProfile="b1dcc9dd-5262-4d8d-a863-c897e6d979b9"
    TerminalLightProfile="3dd28c15-6ba4-4ba0-8289-ab023e6c88fc"

    Gsetting="org.gnome.Terminal.ProfilesList"
    [[ "${1}" == 'Light' ]] && gsettings set "${Gsetting}" default "${TerminalLightProfile}"
    [[ "${1}" == 'Dark' ]] && gsettings set "${Gsetting}" default "${TerminalDarkProfile}"
    gsettings get "${Gsetting}" default
}

If I type Terminal Light in bash terminal, there is no output and the Gnome terminal colour won't change.

But if I paste the function in the terminal manually:

$ Terminal() {
    TerminalDarkProfile="b1dcc9dd-5262-4d8d-a863-c897e6d979b9"
    TerminalLightProfile="3dd28c15-6ba4-4ba0-8289-ab023e6c88fc"

    Gsetting="org.gnome.Terminal.ProfilesList"
    [[ "${1}" == 'Light' ]] && gsettings set "${Gsetting}" default "${TerminalLightProfile}"
    [[ "${1}" == 'Dark' ]] && gsettings set "${Gsetting}" default "${TerminalDarkProfile}"
    gsettings get "${Gsetting}" default
}
$ Terminal Light
'3dd28c15-6ba4-4ba0-8289-ab023e6c88fc'

Then, we can see that gsettings are working, and indeed the gnome terminal profile changes!

Issue

Why is this happening? How can I change gsettings from inside a script or bashfunction defined in ~/.bashrc

Edit

$ type Terminal
bash: type Terminal: command not found
$ Terminal Dark

I am surprised that type Terminal: command not found but Terminal Dark gives no output!

Additionally:

cat Theme.sh
#!/usr/bin/env bash
set -xv
echo $DBUS_SESSION_BUS_ADDRESS
whoami
gsettings set org.gnome.desktop.interface color-scheme 'prefer-light'
gsettings get org.gnome.desktop.interface color-scheme

$ bash ./Theme.sh 
echo $DBUS_SESSION_BUS_ADDRESS
+ echo unix:path=/run/user/1000/bus
unix:path=/run/user/1000/bus
whoami
+ whoami
lamy
gsettings set org.gnome.desktop.interface color-scheme 'prefer-light'
+ gsettings set org.gnome.desktop.interface color-scheme prefer-light
gsettings get org.gnome.desktop.interface color-scheme
+ gsettings get org.gnome.desktop.interface color-scheme
'prefer-light'
$ gsettings get org.gnome.desktop.interface color-scheme
'prefer-dark'

We can see that gsettings get immediately shows different value right after running the script!
