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 Desktop Entry
Specification. The most important aspects of *.desktop files
are summarized below.
</p></div><div class="refsect1" title="Commands"><a name="commands"></a><h2>Commands</h2><div class="variablelist"><dl><dt><span class="term">install</span></dt><dd>
Installs <em class="replaceable"><code>FILE</code></em> to the desktop of the current user.
<em class="replaceable"><code>FILE</code></em> can be a *.desktop file or any
other type of file.
</dd><dt><span class="term">uninstall</span></dt><dd>
Removes <em class="replaceable"><code>FILE</code></em> from the desktop
of the current user.

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.
</p><p class="simpara">
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.

An application launcher can be added to the desktop by installing a
*.desktop file. A *.desktop file consists of a
<span class="emphasis"><em>[Desktop Entry]</em></span> header followed by several
<em class="replaceable"><code>Key</code></em>=<em class="replaceable"><code>Value</code></em> 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
<em class="replaceable"><code>Key</code></em>. This way one can specify different
values for the same <em class="replaceable"><code>Key</code></em> depending on the
currently selected language.
The following keys are often used:
</p><div class="variablelist"><dl><dt><span class="term">Value=1.0</span></dt><dd>
This is a mandatory field to indicate that the *.desktop file
follows the 1.0 version of the specification.
</dd><dt><span class="term">Type=Application</span></dt><dd>
This is a mandatory field that indicates that the *.desktop file
describes an application launcher.
</dd><dt><span class="term">Name=<em class="replaceable"><code>Application Name</code></em></span></dt><dd>
The name of the application.
For example <span class="emphasis"><em>Mozilla</em></span>
</dd><dt><span class="term">GenericName=<em class="replaceable"><code>Generic Name</code></em></span></dt><dd>
A generic description of the application.
For example <span class="emphasis"><em>Web Browser</em></span>
</dd><dt><span class="term">Comment=<em class="replaceable"><code>Comment</code></em></span></dt><dd>
Optional field to specify a tooltip for the application.
For example <span class="emphasis"><em>Visit websites on the Internet</em></span>
</dd><dt><span class="term">Icon=<em class="replaceable"><code>Icon File</code></em></span></dt><dd>
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 <span class="command"><strong>xdg-icon-resource</strong></span>
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.
</dd><dt><span class="term">Exec=<em class="replaceable"><code>Command Line</code></em></span></dt><dd>
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:
</p><div class="variablelist"><dl><dt><span class="term">XDG_UTILS_DEBUG_LEVEL</span></dt><dd>
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:
