xdg-settings — get various settings from the desktop environment
xdg-settings { | get | check } {setproperty} [value]
xdg-settings { --help | --list | --manual | --version }
xdg-settings gets various settings from the desktop environment. For instance, desktop environments often provide proxy configuration and default web browser settings. Using xdg-settings these parameters can be extracted for use by applications that do not use the desktop environment's libraries (which would use the settings natively).
xdg-settings is for use inside a desktop session only. It is not recommended to use xdg-settings as root.
--help--list--manual--versionAn exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned:
1234Get the desktop file name of the current default web browser
xdg-settings get default-web-browser
Check whether the default web browser is firefox.desktop, which can be false even if "get default-web-browser" says that is the current value (if only some of the underlying settings actually reflect that value)
xdg-settings check default-web-browser firefox.desktop
Set the default web browser to google-chrome.desktop
xdg-settings set default-web-browser google-chrome.desktop
