Something like this:
use warnings;
use strict;
use Inline::Files;
my %name_change;
while (<FILE_1>) {
chomp;
next if /^$/;
my ( $k, $v ) = split /,/, $_;
$name_change{$k} = $v;
}
while (<FILE_2>) {
chomp;
s/(uid=)(.+?),/$1$name_change{$2},/ if /uid/;
print $_, $/;
}
__FILE_1__

obiwan,nicol

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).
