a quick look at  perldoc perlfunc or perldoc.com suggests that there is no built-in copy function in perl

Limbic~Region wisely suggests File::Copy which is a core module. (You won't have to install it) and nicely returns (1) on success, (0) on failure and stuffs something useful int $!

Other people tend to do stuff like:

use strict;
system('cp','/path/to/file1','path/to/file2');
my $err_num=$?>>8;
die "bad copy num:$err_num\n" 
    if $err_num;
