<h1 align=center>Loading text into databases</h1>
|
|
<p>The <a href="../../utility/db_load.html">db_load</a> utility can be used to load text into databases.
|
|
The <b>-T</b> option permits non-database 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>.
