The desktop-file-validate program is a tool to validate desktop entry files according to the Desktop Entry specification 1.0. The specification describes a file format to provide information such as name, icon and description for an application. Such a file can then be used as an application launcher and to display the application in the applications menu. For information about the Desktop Entry specification, see http://freedesktop.org/wiki/Specifications/desktop-entry-spec. The desktop entry files are commonly called desktop files. OPTIONS
The following options are supported: --no-warn-deprecated Do not warn about usage of deprecated items that were defined in previous versions of the specification. --warn-kde Warn about usage of KDE extensions to the specification. This includes the use of the KDE Desktop Entry group, of the ServiceTypes, DocPath, Keywords, InitialPreference, Dev, FSType, MountPoint, ReadOnly, UnmountIcon keys, or of the Service, ServiceType and FSDe- vice types.

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.

xdg-desktop-icon honours the following environment variables: XDG_UTILS_DEBUG_LEVEL Setting this environment variable to a non-zero numerical value makes xdg-desktop-icon do more verbose reporting on stderr. Setting a higher value increases the verbosity. EXIT CODES

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. 5 No permission to read one of the files passed on the command line.
