How can I change this setting from a Bash script?
My plan is to enable it only on certain network connections.
You can use
dconf-editor to change this setting. It's under:
com -> canonical -> unity -> lenses
and is called
remote-content-search. As far as I know there are only two options
all. When set to
all the slider is set to "On" in system settings and when it is set to
none the slider is at the "Off" position.
You can change this via the terminal using
gsettings set com.canonical.Unity.Lenses remote-content-search all
Will turn it on while:
gsettings set com.canonical.Unity.Lenses remote-content-search none
will set it to "Off".
Gsettings comes by default in Ubuntu and you can install dconf with:
sudo apt-get install dconf-tools
You don't need dconf to use gsettings.
