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.
