This is a FAQ:
Q:\>perldoc -q password
Found in S:\OS\OSP\OSPI\perl-5.8\5.8.2\lib\pod\perlfaq8.pod
How do I ask the user for a password?
(This question has nothing to do with the web. See a different
FAQ for that.)
There's an example of this in "crypt" in perlfunc). First, you
put the terminal into "no echo" mode, then just read the
password normally. You may do this with an old-style ioctl()
function, POSIX terminal control (see POSIX or its documentation
the Camel Book), or a call to the stty program, with varying
degrees of portability.
You can also do this for most systems using the Term::ReadKey
module from CPAN, which is easier to use and in theory more
portable.
use Term::ReadKey;
ReadMode('noecho');
$password = ReadLine(0);

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
