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 ### ## 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. ## SEE ALSO [**xdg-desktop-icon**(1)](https://www.chedong.com/phpMan.php/man/xdg-desktop-icon/1/markdown), [**xdg-desktop-menu**(1)](https://www.chedong.com/phpMan.php/man/xdg-desktop-menu/1/markdown), [**xdg-mime**(1)](https://www.chedong.com/phpMan.php/man/xdg-mime/1/markdown), **Icon** **theme** **specification**[1] ## 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. ## AUTHORS ### Kevin Krammer Author. ### Jeremy White Author. ## COPYRIGHT Copyright © 2006 ## NOTES 1.
