Thank you. At first I tried:

$output = chomp($_);
[download]

That didn't work. So I found, from the online documentation, how to properly use chomp(). I tried:

$output = $_;
chomp($output);
[download]

... and it worked!

Thank you, also, for those other suggestions. I will also give File::Find, File::Find::Rule and Path::Tiny a try soon.

Well done for consulting the docs - they really are rather good.

You might also want to know that a simple assignment can be chomped as well so you could write this as chomp ($output = $_); instead. Full demo script:

#!/usr/bin/env perl
use strict;
use warnings;

$_ = "foo\n";
print "in: '$_'\n";
chomp (my $output = $_);
print "out: '$output'\n";
[download]

I concur with others in warning against shelling out to find for your original task, not least because of the vagaries of the arguments and output formats of such a utility across platforms. Stick with the modules which come with Perl or are on CPAN for better portability.

In case you didn't know, you can also find out about any perl function with perldoc -f chomp from the command line, or perldoc MODULENAME for any installed perl module. On Unix, you can often see them as manual pages as well: man MODULENAME, but that depends on your distro.
