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/Standards/icon-theme-spec
Installs the icon file indicated by
to the desktop icon system under the name
icon-name. Icon names do not have an extension. If

file exists in the same location as
it will be installed as well.
Removes the icon indicated by
from the desktop icon system. Note that icon names do not have an extension.
Force an update of the desktop icon system. This is only useful if the last call to xdg-icon-resource included the
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 necassery to update the desktop icon system right away.
Normally, xdg-icon-resource checks to ensure that an icon file to be installed in the
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
theme. Applications may install icons under multiple themes but should at least install icons for the default
- --context context

as context which is the default context. Icons to be used as file icons should use
as context. Other common contexts are
- --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
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.

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.
