I do not like the fact that the line number is static and I have to remember to update it if I ever modify the script (I won't remember).
Use __LINE__ for that:
use warnings;
use strict;
printf "I'm in line %d\n", __LINE__;
printf "I'm in line %d\n", __LINE__;
printf "I'm in line %d\n", __LINE__;
__END__
I'm in line 4
I'm in line 5
I'm in line 6

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.
