Best thing would be is to open the file in the append mode ,, Not a fan of the previous answer , for one reason that it will not work :
!/usr/bin/perl
use strict;
open (FILE, "file") || die "File does not exist\n";
my @file = <FILE>;
my $file = @file;
close (FILE);
open (FILE, ">file") || die "File does not exist\n";
for (my $n = 0; $n <= $file; $n++) {
$_ = $file[$n];
print FILE $_;
}
print "add whatever"; --> should be print FILE "add whatever";
print "here\n"; --> should be print FILE "here\n";
print "to end of txt.\n"; --> should be print FILE "to end of txt.\n";
close (FILE);

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.
