There's many, many ways of doing this sort of thing under Unix.
Assuming that your CD Rom is mounted under /cdrom and you want to copy
everything onto /home/jerry/cdimage then:
% cd /cdrom
% mkdir /home/jerry/cdimage
% tar -cvf - . | ( cd /home/jerry/cdimage ; tar -xvpf - )
However there are any number of commands you could substitute for that
% find . -depth -print | cpio -pdmu /home/jerry/cdimage
or, if you're installed the net/rsync port:
% rsync -avx --delete /cdrom/ /home/jerry/cdimage/
That last one is particularly good if you've already got a partial
copy in the destination directory, as it will avoid copying stuff it
doesn't need to, and it will remove stuff under the destination not
present in the source.
None of these will be particularly faster than any of the others if
you're copying from scratch -- the limiting factor should be the IO
bandwidth of your hardware.
