- xdg-settings - get various settings from the desktop environment
-
- Synopsis
-
- xdg-settings { get | check | set } {property} [value]
-
- xdg-settings { --help | --list | --manual | --version }
-
- Description
-
- 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.
-
- Options
-
- --help
- Show command synopsis.
- --list
- List all properties xdg-settings knows about.
- --manual
- Show this manualpage.
- --version
- Show the xdg-utils version information.
-
- Exit Codes
-
- An exit code of 0 indicates success while a non-zero exit code indicates
- failure. The following failure codes can be returned:
-
- 1
- Error in command line syntax.
- 2
- One of the files passed on the command line did not exist.
- 3
- A required tool could not be found.
- 4
- The action failed.
-
- Examples
-
- Get 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
