XDG-MIME(1)									      XDG-MIME(1)

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.

       --help Show command synopsis.

       --manual
	      Show this manualpage.

       --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
