DESCRIPTION
The xdg-icon-resource program can be used to install icon resources into
the desktop icon system in order to illustrate menu entries, to depict
desktop icons or to graphically represent file types.

The desktop icon system identifies icons by name. Depending on the
required size, the choice of icon theme and the context in which the icon
is used, the desktop icon system locates an appropriate icon resource to
depict an icon. Icon resources can be XPM files or PNG files.

The desktop icon system works according to the XDG Icon Theme
Specification at
http://www.freedesktop.org/wiki/Specifications/icon-theme-spec

COMMANDS
install
Installs the icon file indicated by icon-file to the desktop icon
system under the name icon-name. Icon names do not have an
extension. If icon-name is not provided the name is derived from
icon-file. The icon file must have .png or .xpm as extension.
If a corresponding .icon file exists in the same location as
icon-file it will be installed as well.

uninstall
Removes the icon indicated by icon-name from the desktop icon
system. Note that icon names do not have an extension.

forceupdate
Force an update of the desktop icon system. This is only useful
if the last call to xdg-icon-resource included the --noupdate
option.

OPTIONS
--noupdate
Postpone updating the desktop icon system. If multiple icons are
added in sequence this flag can be used to indicate that
additional changes will follow and that it is not necessary to
update the desktop icon system right away.

--novendor
Normally, xdg-icon-resource checks to ensure that an icon file to
be installed in the apps context has a proper 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.

--theme theme
Installs or removes the icon file as part of theme. If no theme
is specified the icons will be installed as part of the default
hicolor theme. Applications may install icons under multiple
themes but should at least install icons for the default hicolor
theme.

--context context
Specifies the context for the icon. Icons to be used in the
application menu and as desktop icon should use apps as context
which is the default context. Icons to be used as file icons
should use mimetypes as context. Other common contexts are
actions, devices, emblems, filesystems and stock.

--size size
Specifies the size of the icon. All icons must be square.
Common sizes for icons in the apps context are: 16, 22, 32, 48,
64 and 128. Common sizes for icons in the mimetypes context are:
16, 22, 32, 48, 64 and 128

--mode mode
mode can be user or system. In user mode the file is
(un)installed for the current user only. In system mode the file
is (un)installed for all users on the system. Usually only root
is allowed to install in system mode.

The default is to use system mode when called by root and to use
user mode when called by a non-root user.

--help Show command synopsis.

--manual
Show this manual page.

--version
Show the xdg-utils version information.

ENVIRONMENT VARIABLES
xdg-icon-resource honours the following environment variables:

XDG_UTILS_DEBUG_LEVEL
Setting this environment variable to a non-zero numerical value
makes xdg-icon-resource do more verbose reporting on stderr.
Setting a higher value increases the verbosity.

XDG_UTILS_INSTALL_MODE
This environment variable can be used by the user or
administrator to override the installation mode. Valid values
are user and system.

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
To install an icon resource to depict a launcher for the application
myfoobar, the company ShinyThings Inc. can use:

xdg-icon-resource install --size 64 shinythings-myfoobar.png

To install an icon for a new application/x-foobar file type one can use:

xdg-icon-resource install --context mimetypes --size 48 ./mime-foobar-48.png application-x-foobar
xdg-icon-resource install --context mimetypes --size 64 ./mime-foobar-64.png application-x-foobar

This will install two icons with the name application-x-foobar but with
different sizes.
