<p>
The <code class="literal">file</code>(1) utility is a UNIX utility
that examines and classifies files, based on information found
in its database of file types, the /etc/magic file. The
following information may be added to your system's /etc/magic
file to enable <code class="literal">file</code>(1) to correctly
identify Berkeley DB database files.
</p>
<p>
The <code class="literal">file</code>(1) utility
<code class="literal">magic</code>(5) information for the standard
System V UNIX implementation of the <code class="literal">file</code>(1)
utility is included in the Berkeley DB distribution for both
big-endian (for example, Sparc) and little-endian (for
example, x86) architectures. See <a class="xref" href="install.html#big-endian" title="Big-endian magic information">Big-endian magic information</a> and <a class="xref" href="install.html#little-endian" title="Little-endian magic information">Little-endian magic information</a>
respectively for this information.
</p>
<p>
The <code class="literal">file</code>(1) utility
<code class="literal">magic</code>(5) information for Release 3.X of
Ian Darwin's implementation of the file utility (as
distributed by FreeBSD and most Linux distributions) is
included in the Berkeley DB distribution. This
<code class="literal">magic.txt</code> information is correct for
both big-endian and little-endian architectures. See the next
section for this information.
