Diskutil is a powerful command-line utility in macOS that allows users to manage disk volumes and partitions. It provides a wide range of functionalities, such as creating, resizing, formatting, and mounting disk volumes. Understanding how to use diskutil is essential for effectively managing storage in the Apple environment.

Examples:

1. Creating a New Disk Volume: To create a new disk volume using diskutil, open the Terminal application and enter the following command:

   diskutil apfs addVolume disk1 APFS NewVolume

   This command creates a new APFS volume named "NewVolume" on the disk labeled "disk1".

2. Resizing a Disk Volume: To resize an existing disk volume, use the following command:

   diskutil apfs resizeContainer disk1 200g

   This command resizes the APFS container on "disk1" to 200GB, adjusting the size of the existing volumes within the container accordingly.

3. Formatting a Disk Volume: To format a disk volume with a specific file system, use the following command:

   diskutil eraseVolume JHFS+ NewVolume disk1s2

   This command formats the volume labeled "NewVolume" on "disk1s2" with the Journaled HFS+ file system.

In case diskutil is not applicable in the Apple environment, an alternative would be to use the Disk Utility graphical interface. Disk Utility provides a user-friendly way to manage disk volumes and partitions, offering similar functionalities as diskutil. To access Disk Utility, go to "Applications" > "Utilities" > "Disk Utility". From there, you can create, resize, format, and mount disk volumes using a visual interface.

In conclusion, diskutil is a crucial tool for managing disk volumes in macOS. By understanding its functionalities and commands, users can effectively control their storage space and optimize their system's performance.
