Ubuntu, one of the most popular Linux distributions, offers a wide range of tools and utilities that make it easy to manage and manipulate files, including creating ISO files. An ISO file, also known as an ISO image, is an archive file that contains a complete copy of a disc, such as a CD, DVD, or Blu-ray disc. In this article, we will explore the different methods of creating ISO files in Ubuntu, including using the command line and graphical user interface (GUI) tools.
Introduction to ISO Files
Before we dive into the process of creating ISO files, it’s essential to understand what they are and why they are useful. ISO files are exact copies of a disc’s contents, including the file system, files, and folders. They can be used to create bootable discs, backup data, and distribute software. ISO files are also useful for creating virtual machines and testing operating systems without having to install them on a physical machine.
Why Create ISO Files in Ubuntu?
There are several reasons why you might want to create ISO files in Ubuntu. Some of the most common reasons include:
Creating a bootable disc to install Ubuntu or other operating systems
Backing up data to a disc or virtual machine
Distributing software or files to others
Creating a virtual machine to test operating systems or software
Archiving data for long-term storage
Creating ISO Files Using the Command Line

Mounting and Verifying ISO Files
Once you have created an ISO file, you may want to mount it to verify its contents or to access the files it contains. To mount an ISO file in Ubuntu, follow these steps:
Open a terminal window and navigate to the folder that contains the ISO file
Use the mount command to mount the ISO file, specifying the file name and a mount point
For example, to mount an ISO file called “myiso.iso” to a mount point called “/mnt”, you would use the following command: mount -o loop myiso.iso /mnt
Verifying the Contents of an ISO File
To verify the contents of an ISO file, you can use the ls command to list the files and folders it contains. You can also use the file command to check the file type and contents of individual files.
Using the file Command
The file command is a useful tool for checking the file type and contents of individual files. To use the file command, follow these steps:
Open a terminal window and navigate to the folder that contains the ISO file
Use the file command to check the file type and contents of individual files
For example, to check the file type and contents of a file called “myfile.txt”, you would use the following command: file myfile.txt
