<p>The <a href="../api_reference/C/db_load.html" class="olink">db_load</a> utility can be used to load text into databases. The <span class="bold"><strong>-T</strong></span> option permits nondatabase applications to create flat-text files that are then loaded into databases for fast, highly-concurrent access. For example, the following command loads the standard UNIX <code class="filename">/etc/passwd</code> file into a database, with the login name as the key item and the entire password entry as the data item:</p>
|
||
<pre class="programlisting">awk -F: '{print $1; print $0}' < /etc/passwd |\
|
||
sed 's/\\/\\\\/g' | db_load -T -t hash passwd.db</pre>
|
||
<p>Note that backslash characters naturally occurring in the text are escaped to avoid interpretation as escape characters by the <a href="../api_reference/C/db_load.html" class="olink">db_load</a> utility.</p>
