Linux DD Command: How to extract files from an ISO image?

Solution 1
If you already have the ISO filesystem in a file on your hard drive (downloaded from the Internet or copied, wholesale, from a CD or DVD), you'll need to mount the file in "loopback" mode. ("loopback" means the source of the filesystem is in fact another file, not a physical device.) As root, something like this would work:
# mkdir /tmp/fedora
# mount /path/to/image.iso /tmp/fedora -o ro,loop -t iso9660
Then you can browse /tmp/fedora using your favorite tools.
You can use dd
to create an iso file from a CD or DVD:
# dd if=/dev/cdrom of=image.iso
Solution 2
I believe dd
can't do that, it just enables raw access to the ISO file itself.
I think you should use the mount
command:
mount -o loop file.iso /mnt

jiggunjer over 8 yearsthis is vague. One can not extract a filesystem from an image, a filesystem isn't data.
