The <b>-T</b> 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 <b>/etc/passwd</b> file into a database, with the login name as the key item and the entire password entry as the data item:</p> <blockquote><pre>awk -F: '{print $1; print $0}' < /etc/passwd |\ sed 's/\\/\\\\/g' | db_load -T -t hash passwd.db</pre></blockquote> <p>Note that backslash characters naturally occurring in the text are escaped to avoid interpretation as escape characters by <a href="../../utility/db_load.html">db_load</a>.</p> <table width="100%"><tr><td><br></td><td align=right><a href="../dumpload/format.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../install/file.html"><img src="../../images/next.gif" alt="Next"></a> </td></tr></table> <p><font size=1>Copyright (c) 1996,2008 Oracle.
