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 manual page.
|
|
--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:
|
|
|
|
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.

|
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
