       xdg-icon-resource - command line tool for (un)installing icon resources


       xdg-icon-resource install [--noupdate] [--novendor] [--theme theme] [--context context]
                         [--mode mode] --size size icon-file [icon-name]

       xdg-icon-resource uninstall [--noupdate] [--theme theme] [--context context] [--mode mode]
                         --size size icon-name

       xdg-icon-resource forceupdate [--theme theme] [--mode mode]

       xdg-icon-resource {--help | --manual | --version}


       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


           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.

           Removes the icon indicated by icon-name 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 --noupdate option.


           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.

           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

           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.

       xdg-icon-resource honours the following environment variables:

           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.

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


       An exit code of 0 indicates success while a non-zero exit code indicates failure. The
       following failure codes can be returned:

           Error in command line syntax.

           One of the files passed on the command line did not exist.

           A required tool could not be found.

           The action failed.

           No permission to read one of the files passed on the command line.

       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.
