As a general thing providing a focused working stand alone sample script illustrating the problem will get you better answers. Consider:
use strict;
use warnings;
my @lines = split /\n/, <<LINES;
token token token
taken token tiki
LINES
chomp @lines;
for my $line (@lines) {
print "$line:\n";
while ($line =~ /token/gi) {
print " >$`|$'<\n";
}
}
Prints:
token token token:
>| token token<
>token | token<
>token token |<
taken token tiki:
>taken | tiki<
while (lc($line) =~ /token/g) { loops until killed because each time through the loop lc($line) is re-evaluated so the regular expression restarts, so don't do that. So long as $line isn't changed the /g makes the regular expression carry on from where it left off last time through the loop, which is what you want.
True laziness is hard work

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).
