As an anonymous monk explained, you can't execute a shell command (of which ">>" is a part) without running a shell!

IPC::Open3 is a somewhat low-level way of doing it, but it's an option. 

use IPC::Open3 qw( open3 );

open(local *OUT_FH, '>>', '/Volumes/Expansion Drive/stuffTGZ/list_xxx_
+dirs.txt') or die $!;

print(OUT_FH "-------------------------------------------------\n");
print(OUT_FH "- $File::Find::name -----------------------------\n");

# Gets closed by open3.
open(local *CHILD_STDIN, '<', '/dev/null') or die $!;

my $pid = open3(
   '<&CHILD_STDIN', '>&OUT_FH', '>&STDERR',
   "/bin/ls" => ( "-l", $File::Find::name ),
);

waitpid($pid, 0);

You can reuse OUT_FH for multiple calls to open3, but you need to reopen CHILD_STDIN each time.
