In the modern world of technology, understanding the command line has become a very important skill. One application that takes advantage of this capability is the creation of ISO files. An ISO file is a file format used to store an operating system or application in a form that can be read by a computer.
In this article, we will discuss why understanding the command line is so important in ISO file creation and how the command line can provide more control in this process.
What is an ISO File?
An ISO file is an archive format that contains identical copies of all the content contained on a disc, such as a CD or DVD. The word “ISO” itself refers to International Organization for Standardization, which is an international body that sets standards for various industries.
ISO files are used for a variety of purposes, such as backing up data, distributing software, and creating USB bootables. ISO files maintain the integrity of the original data and disc structure, making it very useful in a variety of contexts.
ISO files differ from other formats because of their ability to store the entire contents of a disc in a single file. It allows users to create identical digital copies and can be easily accessed through virtual drives.
Advantages of Using ISO Files
ISO files allow for more efficient data storage because they can store the entire contents of a disc in a single file. This saves storage space and makes it easier for users to access data.
ISO files make it easy to distribute and install software because they can be downloaded and installed easily. All files need to be placed in a file that can be accessed by various operating systems, making it easier for users to install software.
Why Use Command Line to Create ISO Files?
The command line gives you complete control over the process of creating ISO files. By using specific commands, you can optimize the creation process and avoid possible errors.
The command line allows you to automate with scripts. You can create scripts that can be run automatically, allowing you to perform repetitive tasks quickly and efficiently.
In some situations, the graphical interface is unavailable or inaccessible. In this condition, the command line is a better choice because it can be accessed directly from the terminal.
Server environments often only support the command line due to better security and control. In an environment like this, using the command line to create an ISO file allows you to optimize the process and avoid errors.

Preparation Before Creating an ISO File
To create an ISO file, you need several devices and software, including:
- A computer or server with sufficient specifications to run the ISO creation process.
- Disk drive (if you created an ISO from a physical CD/DVD).
- PowerISO, mkisofs, or similar software that supports ISO file creation.
- Terminal or command prompt to access the command line.
Before you begin, make sure your work environment is ready. This includes installing the required software and ensuring that you have access to command line. Additionally, it is important to ensure that the directory that will be used as a source is well organized and that no files are corrupted or missing.
If you’re using PowerISO, you can install it by following these steps:
- Download PowerISO from the official website.
- Run the installer and follow the installation instructions.
- Once the installation is complete, open the PowerISO and make sure the software is accessible via command line by typing poweriso in the terminal or command prompt.
Steps to Create an ISO File from the Command Line
Basic Commands in the Command Line
Before you start creating an ISO file, it’s important to understand some of the basic commands that are often used in command line. These commands will help you navigate and manage files and directories easily:
- dir (on Windows) or ls (on Linux/Mac): Used to display the contents of the current directory.
- cd: Used to move to another directory.
- mkdir: Create a new directory.
- cp (on Linux/Mac) or copy (on Windows): Copying a file or directory.
Creating an ISO File from a Folder or Directory
To create an ISO file from a folder or directory, you can use a command like mkisofs (on Linux) or equivalent software on Windows like PowerISO. Here are the general steps to use mkisofs:
- Navigate to the directory that contains the source folder with the cd command.
- Run mkisofs commands with output specifications and source directories. General syntax:
mkisofs -o output.iso /path/to/source_directory-o output.iso: Specifies the output ISO file name.
/path/to/source_directory: Path to the source directory you want to create into an ISO file.
For example, to create an ISO file named backup.iso from a folder named backup_folder, run:
mkisofs -o backup.iso /home/user/backup_folderThis will result in an ISO file named backup.iso in the current directory.
