Here's how I would approach this (not tested)
use strict;
use Fcntl ':flock';
my $iniFile = 'config.ini';
if (open my $ini, "+<$iniFile"){
if (flock $ini, LOCK_EX){
my @data = <$ini>;
# Work with @data -- delete lines, update lines, etc.
if (truncate($ini, 0) and seek($ini, 0, 0)){
print "Can't write to $iniFile : $!\n"
unless print $ini @data;
}else{
print "Can't truncate/seek : $!\n";
}
}else{
print "Can't lock : $!\n";
}
close $ini;
}else{
print "Can't open $iniFile : $!\n";
}

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).
