xdg−desktop−icon {−−help | −−manual | −−version} |
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.
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.
−−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

−−version
Show the xdg−utils version information.
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.
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.
5
No permission to read one of the files passed on the command line.
xdg-icon-resource(1)
The company ShinyThings Inc. has developed an application named "WebMirror" and would like to add a launcher for for on the desktop. The company will use "shinythings" as its vendor id. In order to add the application to the desktop there needs to be a .desktop file for the application:
shinythings−webmirror.desktop:
[Desktop Entry]
Encoding=UTF−8
Type=Application
Exec=webmirror
Icon=shinythings−webmirror
Name=WebMirror
Name[nl]=WebSpiegel
Now the xdg−desktop−icon tool can be used to add the webmirror.desktop file to the desktop:
xdg−desktop−icon install ./shinythings−webmirror.desktop
To add a README file to the desktop as well, the following command can be used:
xdg−desktop−icon install ./shinythings−README
