No need to call test to see if a file exists. We have -e in Perl, too. We even have File::Copy, so you don't need to cat a file. Path::Tiny wraps all the path related operations nicely:
#!/usr/bin/perl
# Untested!
use Path::Tiny;
my @files = ( ... );
sub find_files {
my $filename = shift;
my $path = 'Path::Tiny'->cwd;
my $file = path($filename)->basename;
if (-e $filename) {
path($filename)->copy("$path/$file");
} else {
open my $OUT, '>', "$path/$file" or die $!;
print {$OUT} "Unable to find $filename\n";
}
}
Note that -e returns true for directories, too, so you might need a different test (-f maybe?). Also, you should check the return value of copy.

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).
