The command line approach to disk erasure in macOS is a bit different and it requires precise syntax to insure that you are erasing the proper disk, making this method of erasing any disk only appropriate for advanced Mac users.

You can choose any common file system format the disk to after it has been erased, including ExFAT, FAT32, HFS, or JHFS.

The entire target disk is erased, all data on the target disk is destroyed using this approach, with no volumes or partitions or any data remaining.

Do not misunderstand that, otherwise you will inevitably permanently lose data when it is erased and destroyed.

Remember the command line is unforgiving, if you are not comfortable at the command line it would be much more appropriate to erase and format a disk using Disk Utility in the standard interface of Mac OS X.

If you are unsure, you can find the disk ID node with diskutil info DISK NAME grep Device.

As always, be sure you change the disk node as appropriate for your disk.

Format is the specific file system name you want to erase it as (HFS, etc.).

Name is the (new) volume name (subject to file system naming restrictions), or can be specified as noformat to skip initialization (newfs).

Single User Mode alone is not sufficient to erase the actively booted operating system.
