> '--copy-contents'
> If copying recursively, copy the contents of any special files
> (e.g., FIFOs and device files) as if they were regular files.
> This means trying to read the data in each source file and writing
> it to the destination. It is usually a mistake to use this
> option, as it normally has undesirable effects on special files
> like FIFOs and the ones typically found in the `/dev' directory.
> +-- In most cases, `cp -R --copy-contents' will hang indefinitely
> | trying to read from FIFOs and special files like `/dev/console',
> | and it will fill up your destination disk if you use it to copy
> +-- `/dev/zero'. This option has no effect unless copying
> recursively, and it does not affect the copying of symbolic links.
