One way to do it is to generate a lookup hash keyed on your search data. Here's a starting point:
use warnings;
use strict;
my @file1 =
(
'1141286452,ServerA,Disk Full',
'1141286737,ServerB,Net Down',
'1141286737,ServerC,Disk Full'
);
my @file2 =
(
'1141286737,ServerB,Net Down',
'1141286780,ServerD,Bit Bucket Missing'
);
my %file1LookUp;
push @{$file1LookUp{$file1[$_ - 1]}}, $_ for (1..@file1);
for (@file2) {
print "Matched $_ at line(s) @{$file1LookUp{$_}}\n" if exists $fil
+e1LookUp{$_};
}
Prints:
Matched 1141286737,ServerB,Net Down at line(s) 2

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).
