<h1>Description</h1>
<a name="3"><!--meow--></a> <a name="4"><!--meow--></a>
<p>The db_verify utility verifies the structure of one or more
files and the databases they contain.
<p>The options are as follows:
<p><dl compact>
<p><dt><b>-h</b><dd>Specify a home directory for the database environment; by
default, the current working directory is used.
<p><dt><b>-N</b><dd>Do not acquire shared region locks while running. Other problems such as
potentially fatal errors in Berkeley DB will be ignored as well. This option
is intended only for debugging errors and should not be used under any
other circumstances.
<p><dt><b>-q</b><dd>Suppress the printing of any error descriptions, simply exit success or
failure.
<p><dt><b>-V</b><dd>Write the version number to the standard output and exit.
</dl>
<p>If the file being verified contains databases using non-default
comparison or hashing functions, the db_verify utility may
not be used for verification, as it will likely always return failure.
Such files must be verified explicitly, using the <a href="../api_c/db_verify.html">DB-&gt;verify</a> function,
after setting the correct comparison or hashing functions.
<p>The db_verify utility may be used with a Berkeley DB environment (as described for the
<b>-h</b> option, the environment variable <b>DB_HOME</b>, or,
because the utility was run in a directory containing a Berkeley DB
environment). In order to avoid environment corruption when using a Berkeley DB
environment, db_verify should always be given the chance to detach from
the environment and exit gracefully. To cause db_verify to release all
environment resources and exit cleanly, send it an interrupt signal
(SIGINT).
<p>The db_verify utility exits 0 on success, and &gt;0 if an error occurs.
<h1>Environment Variables</h1>
<p><dl compact>
<p><dt>DB_HOME<dd>If the <b>-h</b> option is not specified and the environment variable
DB_HOME is set, it is used as the path of the database home, as described
in <a href="../api_c/env_open.html">DBENV-&gt;open</a>.
</dl>
