IMO the best argument for not using a system utility if there's an equivalent Perl-based solution: portability. File::Copy will work on any system that can run Perl. cp won't work on any platform where the file duplication utility isn't called that.

File::Copy::Link(3pm)					User Contributed Perl Documentation				     File::Copy::Link(3pm)

NAME
File::Copy::Link - Perl extension for replacing a link by a copy of the linked file. SYNOPSIS
use File::Copy::Link; copylink 'file.lnk'; use File::Copy::Link qw(safecopylink); safecopylink 'file.lnk'; DESCRIPTION
"copylink" reads the filename linked to by the argument and replaced the link with a copy of the file. It opens a filehandle to read from the link, deletes the link, and then copies the filehandle back to the link. "safecopylink" does the same as "copylink" but without the open-and-delete manouvre. Instead, it uses "File::Spec::Link" to find the target of the link and copies from there. This module is mostly a wrapper round "File::Spec::Link::linked" and "File::Copy::copy", the functionality is available in a command line script copylink. EXPORT Nothing by default, can export "copylink", `"safecopylink". SEE ALSO
