XDG-DESKTOP-ICON(1) XDG-DESKTOP-ICON(1) NAME
xdg-desktop-icon - command line tool for (un)installing icons to the desktop SYNOPSIS
xdg-desktop-icon install [--novendor] FILE xdg-desktop-icon uninstall FILE xdg-desktop-icon {--help --manual --version} DESCRIPTION
The xdg-desktop-icon program can be used to install an application launcher or other file on the desktop of the current user. An application launcher is represented by a *.desktop file. Desktop files are defined by the freedesktop.org Desktop Entry Specification. The most important aspects of *.desktop files are summarized below. COMMANDS
install Installs FILE to the desktop of the current user. FILE can be a *.desktop file or any other type of file. uninstall Removes FILE from the desktop of the current user. OPTIONS
--novendor Normally, xdg-desktop-icon checks to ensure that a *.desktop file to be installed has a vendor prefix. This option can be used to disable that check. A vendor prefix consists of alpha characters ([a-zA-Z]) and is terminated with a dash ("-"). Companies and organizations are encouraged to use a word or phrase, preferably the organizations name, for which they hold a trademark as their vendor prefix. The purpose of the vendor prefix is to prevent name conflicts. --help Show command synopsis. --manual Show this manualpage. --version Show the xdg-utils version information. DESKTOP FILES
An application launcher can be added to the desktop by installing a *.desktop file. A *.desktop file consists of a [Desktop Entry] header followed by several Key=Value lines. A *.desktop file can provide a name and description for an application in several different languages. This is done by adding a language code as used by LC_MESSAGES in square brackets behind the Key. This way one can specify different values for the same Key depending on the currently selected language. The following keys are often used: Value=1.0 This is a mandatory field to indicate that the *.desktop file follows the 1.0 version of the specification. Type=Application This is a mandatory field that indicates that the *.desktop file describes an application launcher. Name=Application Name The name of the application. For example Mozilla GenericName=Generic Name A generic description of the application. For example Web Browser Comment=Comment Optional field to specify a tooltip for the application. For example Visit websites on the Internet Icon=Icon File The icon to use for the application. This can either be an absolute path to an image file or an icon-name. If an icon-name is provided an image lookup by name is done in the user's current icon theme. The xdg-icon-resource command can be used to install image files into icon themes. The advantage of using an icon-name instead of an absolute path is that with an icon-name the application icon can be provided in several different sizes as well as in several differently themed styles. Exec=Command Line The command line to start the application. If the application can open files the %f placeholder should be specified. When a file is dropped on the application launcher the %f is replaced with the file path of the dropped file. If multiple files can be specified on the command line the %F placeholder should be used instead of %f. If the application is able to open URLs in addition to local files then %u or %U can be used instead of %f or %F.
