0:      GUID_partition_scheme                        *500.3 GB   disk0
1:                        EFI EFI                     209.7 MB   disk0s1
2:          Apple_CoreStorage Macintosh HD            499.4 GB   disk0s2
3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

Disk /dev/disk1 (Internal, Virtual):
#:                       TYPE NAME                   SIZE       IDENTIFIER

In this example output, we can see that there are two disks connected to the Mac. Disk0 is the internal physical disk, which has a GUID partition table and a CoreStorage file system. Disk1 is the virtual disk created by the CoreStorage volume on disk0. The Macintosh HD volume is unencrypted, and the operating system version is macOS 11.3.1.

Conclusion

With just one command, you can quickly get an overview of disk names, sizes, partition map types, file system formats, and OS versions. This command is especially useful for troubleshooting disk-related issues or verifying disk configurations.
