Linux Bin to ISO - Shell-Bash

Introduction

In this tutorial, we will guide you through the process of converting a Linux binary file into an ISO image using Shell-Bash scripting. This can be useful for creating bootable CDs or DVDs from a compiled Linux executable file.

Prerequisites

Before getting started, make sure you have the following prerequisites:

• Linux operating system
• Basic knowledge of Shell-Bash scripting
• The genisoimage tool installed (can be installed using package managers like apt or yum)

Step 1: Convert Binary to ISO

To convert a Linux binary file to an ISO image, follow these steps:

1. Create a new directory to organize the files:

   mkdir iso_conversion
   cd iso_conversion
   

2. Copy your binary file to the iso_conversion directory:

   cp /path/to/binary_file .
   

3. Rename the binary file to boot.bin:

   mv binary_file boot.bin
   

4. Create a boot directory inside iso_conversion to store the binary file:

   mkdir boot
   cp boot.bin boot/
   

5. Create a boot.catalog file with the following content:

   boot.catalog
   -boot-info-table
   -no-emul-boot
   -boot-load-size 4
   -boot-load-segment 0x07C0
   -m boot.bin
   

6. Create a mkisofs.sh script file with the following content:

   #!/bin/bash
   genisoimage -quiet -V "ISO_NAME" -input-charset iso8859-1 -o ../final_image.iso -b boot.bin -c boot.catalog .
   

7. Make the mkisofs.sh script executable:

   chmod +x mkisofs.sh
   

8. Run the script to create the ISO image:

   ./mkisofs.sh
   

9. The ISO image will be created as final_image.iso in the parent directory.

Conclusion

In this tutorial, we have learned how to convert a Linux binary file to an ISO image using Shell-Bash scripting. You can now use this ISO image to create bootable CDs or DVDs. Feel free to modify the script according to your specific requirements. Happy coding!
