<h1 align=center>Loading text into databases</h1>
19
 
<p>The <a href="../../utility/db_load.html">db_load</a> utility can be used to load text into databases.
20
 
The <b>-T</b> option permits nondatabase applications to create
21
 
flat-text files that are then loaded into databases for fast,
22
 
highly-concurrent access.  For example, the following command loads the
23
 
standard UNIX <b>/etc/passwd</b> file into a database, with the login
24
 
name as the key item and the entire password entry as the data item:
25
 
<p><blockquote><pre>awk -F: '{print $1; print $0}' &lt; /etc/passwd |\
26
 
        sed 's/\\/\\\\/g' | db_load -T -t hash passwd.db</pre></blockquote>
27
 
<p>Note that backslash characters naturally occurring in the text are escaped
28
 
to avoid interpretation as escape characters by <a href="../../utility/db_load.html">db_load</a>.
