I use unpack ...
my $file = 'Rajesh.1202242219';
my ($name, $datetime) = split /\./, $file;
my ( $y, $m, $d, $hr, $min ) = unpack 'A2A2A2A2A2', $datetime;
print "( $y, $m, $d, $hr, $min )";
# returns .. ( 12, 02, 24, 22, 19 )
As Occam said: Entia non sunt multiplicanda praeter necessitatem.

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).

or How to display code and escape characters
are good places to start.
