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.

www.freedesktop.org/wiki/Standards/desktop-entry-spec

Environment Variables

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

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.

Examples

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
