<h4 class="subsection">2.12.1 Mimeview Invocation</h4>
<p>The following table summarizes options specific for <code>mimeview</code>:
</p>
<dl compact="compact">
<dt><samp>-a[<var>type-list</var>]</samp></dt>
<dt><samp>--no-ask[=<var>type-list</var>]</samp></dt>
<dd><p>By default <code>mimeview</code> asks for confirmation before running
interpreter to view a message. If this option is used without
argument, it disables the default behavior for all message
types. Otherwise, if argument <var>type-list</var> is given, it specifies
a comma-separated list of MIME types for which no questions should be
asked. Elements of this list may include shell-style globbing
patterns, e.g. setting
</p>
<div class="example">
<pre class="example">--no-ask='text/*,image/jpeg'
</pre></div>
<p>will disable prompting before displaying any textual files, no
matter what their subtype is, and before displaying files with
type ‘<samp>image/jpeg</samp>’.
</p>
<p>Notice, that when the long form is used, its argument
must be separated from the option by a single equal sign, as shown
in the example above. When the short form (<samp>-a</samp>) is used, its argument
must follow the option immediately, without any intervening whitespace,
e.g. <samp>-a'text/*'</samp>).
</p>
</dd>
<dt><samp>-d[<var>flags</var>]</samp></dt>
<dt><samp>--debug[=<var>flags</var>]</samp></dt>
<dd><p>Enables debugging output. <var>Flags</var> is a sequence of characters
specifying the desired debugging level. Following characters are
meaningful in <var>flags</var>:
</p>
<dl compact="compact">
<dt>g</dt>
<dd><p>Enables debugging of <samp>mime.types</samp> parser
</p>
</dd>
<dt>l</dt>
<dd><p>Enables debugging of <samp>mime.types</samp> lexical analyzer (warning:
produces <em>very</em> copious output)
</p>
</dd>
<dt>1</dt>
<dd><p>Prints basic information about actions to be executed and reports
about exit status of executed commands.
</p>
</dd>
<dt>2</dt>
<dd><p>Additionally displays each file name along with its MIME type
</p>
</dd>
<dt>3</dt>
<dd><p>Additionally traces the process of looking up the matching entry
in <code>mailcap</code> files.
</p>
</dd>
<dt>digits from 4 to 9</dt>
<dd><p>The same as 3, currently.
</p></dd>
</dl>
<p>If <var>flags</var> are not given, the default ‘<samp>9</samp>’ is assumed.
</p>
</dd>
<dt><samp>--metamail[=<var>file</var>]</samp></dt>
<dd><p>Run <code>metamail</code> to display files, instead of using the internal
mechanisms. If <var>file</var> is specified, it is taken as
<code>metamail</code> command line.
</p>
</dd>
<dt><samp>-h</samp></dt>
<dt><samp>--no-interactive</samp></dt>
<dt><samp>--print</samp></dt>
<dd><p>This options tells <code>mimeview</code> that it should run in
non-interactive mode. In this mode prompting is disabled, and
the normal mailcap <code>command</code> field is not executed. Instead
<code>mimeview</code> will execute the command specified in
the <code>print</code> field. If there is nothing in the print field,
the mailcap entry is ignored and the search continues for a matching
mailcap entry that does have a <code>print</code> field.
</p>
<p>Notice, that unlike in <code>metamail -h</code>, this option does
not force <code>mimeview</code> to send the output to the printer
daemon.
</p>
<p>When used with <samp>--metamail</samp> option, this option passes
<samp>-h</samp> flag to the invocation of <code>metamail</code>.
</p>
<p>By default <code>mimeview</code> behaves as if given
<samp>--no-interactive</samp> option whenever its standard input is not
a tty device.
</p>
</dd>
<dt><samp>-n</samp></dt>
<dt><samp>--dry-run</samp></dt>
<dd><p>Do not do anything, just print what would be done. Implies
<samp>--debug=1</samp>, unless the debugging level is set up explicitly.
</p>
</dd>
<dt><samp>-t <var>file</var></samp></dt>
<dt><samp>--mimetypes <var>file</var></samp></dt>
<dd><p>Use <var>file</var> as <samp>mime.types</samp> file. If <var>file</var> is a
directory, use <samp><var>file</var>/mime.types</samp>
</p></dd>
