    5.6: How can I copy a file?

    (contributed by brian d foy)

    Use the "File::Copy" module. It comes with Perl and can do a true copy
    across file systems, and it does its magic in a portable fashion.

    use File::Copy;

    copy( $original, $new_copy ) or die "Copy failed: $!";

    If you can't use "File::Copy", you'll have to do the work yourself: open
    the original file, open the destination file, then print to the
    destination file as you read the original. You also have to remember to
    copy the permissions, owner, and group to the new file.

    The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
    are not necessarily experts in every domain where Perl might show up,
    so please include as much information as possible and relevant in any
    corrections. The perlfaq-workers also don't have access to every
    operating system or platform, so please include relevant details for
    corrections to examples that do not work on particular platforms.
    Working code is greatly appreciated.

    If you'd like to help maintain the perlfaq, see the details in
    perlfaq.pod.
