Create an ISO

Creating an ISO image from almost any media is straightforward in Linux. Run a dd or mkisofs with the inputs:

    • state what to use as the source and
    • state the name and address of the final file.

In this example, we're going to copy the contents of a disk in the DVD drive (/dev/cdrom) to an ISO image file. We will use the dd command to convert and copy a file. Using the following flags:

    • if defines the input file
    • of defines the output file
    • iso is for the ISO image file.

Create from a CD or a DVD

dd if=/dev/cdrom of=/home/user/my.iso

Create from files in a directory

To create an ISO image from files request to have the files within a directory. We use the mkisofs command, state an input directory, and name the ISO file you are to create, using the flag:

    • -o defines the name and address of the file
mkisofs -o /home/user/test.iso /source/directory/
