drutil (with examples)

Drutil is a command-line utility on macOS that allows users to interact with DVD burners. It provides various functionalities such as ejecting discs, burning ISO9660 filesystems onto DVDs, and more. In this article, we will explore eight different use cases of the drutil command and understand their purposes and outputs.

Use Case 1: Ejecting a Disk

Code: drutil eject

Motivation: This command is useful when we want to quickly eject a disk from the drive without having to physically press the eject button on the drive.

Explanation: The eject subcommand instructs drutil to eject the currently inserted disk from the drive.

Example Output: The disk tray will open, and a message confirming the disk ejection will be displayed.

Use Case 2: Burning a Directory as an ISO9660 Filesystem onto a DVD

Code: drutil burn -noverify -eject -iso9660

Motivation: This command allows us to create an ISO9660 filesystem image from a directory and burn it onto a DVD. It is useful for creating bootable DVDs, archiving data, or creating installation media.

Explanation:

• -noverify: Disables the verification process after burning the DVD. This can speed up the burning process, but it won’t ensure the accuracy of the burned data.
• -eject: Ejects the DVD automatically after burning is complete.
• -iso9660: Specifies the format of the filesystem to be burned as ISO9660.

Example Output: The command will start burning the directory onto the DVD in ISO9660 format. Once completed, the DVD will be ejected, and a success message will be displayed.
