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 application'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 type-subtype must be installed with the xdg-icon-resource
    command in the mimetypes context. For example the filetype application/
    vnd.oasis.opendocument.text requires an icon named
    application-vnd.oasis.opendocument.text to be installed (unless the file
    type recommends another icon name).
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 manual page.
--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.

MIME applications associations specification

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 follows.

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
