xdg-settings(1)


NAME

   xdg-settings - get various settings from the desktop environment

SYNOPSIS

   xdg-settings {get | check | set} {property} [subproperty] [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 manual page.

   --version
       Show the xdg-utils version information.

PROPERTIES

   When using xdg-settings to get, check or set a destkop setting,
   properties and possibly sub-properties are used to specify the setting
   to be changed.

   Some properties (such as default-web-browser) fully describe the
   setting to be changed. Other properties (such as
   default-url-scheme-handler) require more information (in this case the
   actual scheme to set the default handler for) which must be provided in
   a sub-property.

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

   Set the default mailto URL scheme handler to be evolution.desktop

               xdg-settings set default-url-scheme-handler mailto evolution.desktop
