.SH "DESCRIPTION"
.PP
The xdg\-mime program can be used to query information about file types and to add descriptions for new file types.
.SH "COMMANDS"
.TP
query
Returns information related to the file type of
\fIFILE\fR.
.sp
The
\fIquery\fR
option is for use inside a desktop session only. It is not recommended to use xdg\-mime query as root.
.sp
The following queries are supported:
.sp
\fIfiletype\fR: Returns the file type of
\fIFILE\fR
in the form of a MIME type.
.sp
\fIdefault\fR: Returns the default application that the desktop environment uses for opening
\fIFILE\fR. The default applications is identified by its *.desktop file.
.TP
default
Ask the desktop environment to make
\fIapplication\fR
the default application for opening files of type
\fImimetype\fR. An application can be made the default for several file types by specifying multiple mimetypes.
.sp
\fIapplication\fR
is the desktop file id of the application and has the form vendor\-name.desktop
\fIapplication\fR
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.
.sp
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.
.sp
The
\fIdefault\fR
option is for use inside a desktop session only. It is not recommended to use xdg\-mime default as root.
.TP
install
Adds the file type descriptions provided in
\fImimetypes\-file\fR
to the desktop environment.
\fImimetypes\-file\fR
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
\fImajor\fR\-\fIminor\fR
must be installed with the
\fBxdg\-icon\-resource\fR
command in the
\fImimetypes\fR
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.
.TP
uninstall
Removes the file type descriptions provided in
\fImimetypes\-file\fR
and previously added with
\fBxdg\-mime install\fR
from the desktop environment.
\fImimetypes\-file\fR
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.
.SH "OPTIONS"

\fB\-\-user\fR

.TP
\fB\-\-version\fR
