One pretty standard way is to just pass the file(s) on the command line and parse each file one after the next:
use strict;
use warnings;
use Getopt::Long;
GetOptions(
'id1=s' => \my $id1,
'id2=s' => \my $id2,
);
for my $file (@ARGV) {
open (my $filename, "<", $file) or die "Could not open $file, $!";
while (<$filename>){
while (/$id1/g && /$id2/g)
{
print "$file:$.\n";
}
}
close ($filename);
}
Called like:
script.pl --id1="test1|test2" --id2="test3|test4" file1.txt file2.txt
Regarding your glob problem, post a small sample of your input file so others can reproduce the issue.

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).
