Unfortunately, perl is completely missing the 'Telepathy::File' module, last I checked, and will thus need to actually open files to read them, just like every other computer program would.
What do you need to put in another array for post processing? The filename? Maybe something like this:
my @files = grep {
open my $fh, '<', $_ or die "Failed to open $_: $!";
my $rc = 0;
my $l;
while (!$rc && defined($l = <$fh>)) {
$rc++ if $l =~ /^source/;
}
$rc
} @arr1;
(Untested.) Maybe. Hard to tell without more info from you.

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).

or How to display code and escape characters
are good places to start.
