ISO images are file system image files which were traditionally used to burn images to CDs and DVDs. They are still used to distribute a large collection of files in use-cases such as GNU/Linux distributions.

Extracting ISO images[edit]

7zip is one option for extracting files from a install ISO image. You can use other options. It can be installed with either apt-get install p7zip-full or dnf install p7zip p7zip-plugins depending on distribution. One it's installed it's possible to extract a ISO image with 7z x filename.iso

Tips from IRC[edit]

  • 20:41 <@nux> dd if=/dev/sda2 of=sda2.iso will create sda2.iso which contains the whole partition
  • 20:41 <@nux> you can then mount that, compress it, copy it, burn it on a dvd and give it to your grandmother
  • 20:42 <+context> a dd of a CD will be iso9660
  • 20:42 <@nux> just dd if=/dev/sda2 of=sda2.allthedataonsda2inthisfile

Backup zero![edit]

  • 20:43 <+context> dd if=/dev/zero of=/dev/sda2
