NAME

       xdg-mime - command line tool for querying information about file type
       handling and adding descriptions for new file types

SYNOPSIS

       xdg-mime query {filetype default} ...

       xdg-mime default application mimetype(s)

       xdg-mime install [--mode mode] [--novendor] mimetypes-file

       xdg-mime uninstall [--mode mode] mimetypes-file

       xdg-mime {--help --manual --version}

DESCRIPTION

       The xdg-mime program can be used to query information about file types
       and to add descriptions for new file types.

COMMANDS

       query  Returns information related to file types.

              The query option is for use inside a desktop session only. It is
              not recommended to use xdg-mime query as root.

              The following queries are supported:

              query filetype FILE: Returns the file type of FILE in the form
              of a MIME type.

              query default mimetype: Returns the default application that the
              desktop environment uses for opening files of type mimetype. The
              default application is identified by its *.desktop file.

       default
              Ask the desktop environment to make application the default
              application for opening files of type mimetype. An application
              can be made the default for several file types by specifying
              multiple mimetypes.

              application is the desktop file id of the application and has
              the form vendor-name.desktop application must already be
              installed in the desktop menu before it can be made the default
              handler. The aplication’s desktop file must list support for all
              the MIME types that it wishes to be the default handler for.

              Requests to make an application a default handler may be subject
              to system policy or approval by the end-user. xdg-mime query can
              be used to verify whether an application is the actual default
              handler for a specific file type.

              The default option is for use inside a desktop session only. It
              is not recommended to use xdg-mime default as root.

       install
              Adds the file type descriptions provided in mimetypes-file to
              the desktop environment.  mimetypes-file must be a XML file that
              follows the freedesktop.org Shared MIME-info Database
              specification and that has a mime-info element as its document
              root. For each new file type one or more icons with name
              major-minor must be installed with the xdg-icon-resource command
              in the mimetypes context. For example the
              application/vnd.oasis.opendocument.text filetype requires an
              icon by the name of application-vnd.oasis.opendocument.text to
              be installed.

       uninstall
              Removes the file type descriptions provided in mimetypes-file
              and previously added with xdg-mime install from the desktop
              environment.  mimetypes-file must be a XML file that follows the
              freedesktop.org Shared MIME-info Database specification and that
              has a mime-info element as its document root.

OPTIONS

       --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.

       --novendor
              Normally, xdg-mime checks to ensure that the mimetypes-file to
              be installed 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.

       --manual

       --version
              Show the xdg-utils version information.

ENVIRONMENT VARIABLES

       xdg-mime honours the following environment variables:

       XDG_UTILS_DEBUG_LEVEL
              Setting this environment variable to a non-zero numerical value
              makes xdg-mime 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-icon-resource(1), xdg-desktop-menu(1)

EXAMPLES

       xdg-mime query filetype /tmp/foobar.png

       Prints the MIME type of the file /tmp/foobar.png, in this case
       image/png

       xdg-mime query default image/png

       Prints the .desktop filename of the application which is registered to
       open PNG files.

       xdg-mime install shinythings-shiny.xml

       Adds a file type description for "shiny"-files. "shinythings-" is used
       as the vendor prefix. The file type description could look as folows.

       shinythings-shiny.xml:

       <?xml version="1.0"?>
       <mime-info xmlns=’http://www.freedesktop.org/standards/shared-mime-info’>
         <mime-type type="text/x-shiny">
           <comment>Shiny new file type</comment>
           <glob pattern="*.shiny"/>
           <glob pattern="*.shi"/>
         </mime-type>
       </mime-info>

       An icon for this new file type must also be installed, for example
       with:

       xdg-icon-resource install --context mimetypes --size 64 shiny-file-icon.png text-x-shiny
