NAME
xdg-desktop-icon - command line tool for (un)installing icons to the desktop
SYNOPSIS
xdg-desktop-icon install [--novendor] 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.

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:
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.
