Dave, Here is the script I use when using system(): 
#! /usr/bin/perl
use strict;
use warnings;

my @files = system "find . -ls";

foreach my $file (@files) {
    chomp $file;
        print "$file\n";
}

And it outputs the following (I deleted the userid column): 
1105134059    2 drwxr-xr-x   3 .... users        2048 Feb  5 09:40 .
1105135378    1 -rw-r--r--   1 .... users         506 Feb  3 10:54 ./t
+est.pl
1105135090    1 -rw-r--r--   1 .... users          93 Jan 24 15:41 ./c

Notice the trailing 0? If I replace my @files = system "find . -ls"; with my @files = `find . -ls`;, I get the same output, except the trailing 0 is missing.

I understand why system() prints out the trailing 0 (it's the exit status of find()), but why is it also outputting everything find() outputs? I thought it should only return the exit status.
