Create an ISO Image File in Linux
Have you ever wanted to create an identical copy of an original CD, DVD, or Blu-ray disc? By using the following commands, contents of an optical disc or local directory can be perfectly represented in a single ISO file.
Create an ISO image from optical media
In this example, we're going to copy the contents of a disk in the CD/DVD drive (/dev/cdrom) to an ISO image file. Open a terminal window and type the following at the command line.
dd if=/dev/cdrom of=/directory/example.iso
- dd is the program used to convert and copy a file.
- if defines an input file.
- of defines an output file.
- iso is the resulting ISO image file.
Create an ISO image from files in a directory
To create an ISO image from files within a directory is just as simple. State an output directory and name of the ISO to create, along with a source directory. For example:
mkisofs -o /home/linuxlookup/example.iso /source/directory/
