<p>For each file given in its command line, <code>mimeview</code> attempts
to autodetect its type and invoke an appropriate file viewer.
</p>
<p>To detect the file type, <code>mimeview</code> uses <samp>mime.types</samp>
file. This file is a part of Common UNIX Printing System,
<a href="../mime/mime_002etypes.html#mime_002etypes">mime.types</a> in <cite>mime.types man page</cite>. By default
<code>mimeview</code> searches for <samp>mime.types</samp> in
<samp>$prefix/etc/cups/</samp><a name="DOCF2" href="#FOOT2"><sup>2</sup></a>, however its exact location can be specified
at runtime as well (see <samp>--mimetypes</samp> below).
</p>
<p>Once file MIME type is successfully determined, <code>mimeview</code>
consults <samp>mailcap</samp> files in order to determine how to display
the file. It does so essentially in the same manner as
<code>metamail</code> utility, i.e., it scans all files specified
in <code>METAMAIL</code> environment variable until it finds an entry
describing the desired file format or until the list of files is
exhausted. If <code>METAMAIL</code> variable is not set, <code>mimeview</code>
uses the following default path instead:
</p>
<div class="example">
<pre class="example">$HOME/.mailcap:/usr/local/etc/mailcap:\
/usr/etc/mailcap:/etc/mailcap:\
/etc/mail/mailcap:/usr/public/lib/mailcap
</pre></div>

<tr><td align="left" valign="top">• <a href="Mimeview-Config.html#Mimeview-Config" accesskey="2">Mimeview Config</a>:</td><td> </td><td align="left" valign="top">
</td></tr>
</table>
<div class="footnote">
<hr>
<h4 class="footnotes-heading">Footnotes</h4>
<h3><a name="FOOT2" href="#DOCF2">(2)</a></h3>
<p>The exact location is determined at
configuration time by setting environment variable
<code>DEFAULT_CUPS_CONFDIR</code>. On most sites running
</p>
<div class="example">
<pre class="example">./configure DEFAULT_CUPS_CONFDIR=/etc/cups
</pre></div>
<p>should be recommended.</p>
