The driveinfo command gets detailed information about a specific drive. The script parses property lists emitted by the diskutil command to compile the information. If the drive contains a GUID Partition Table (GPT), then detailed information about each partition is also included in a tabular form. This also allows free space on a drive, using a GPT, to be identified.
The gpt command can be used to view the actual stored GPT values in in a tabular form. Starting with macOS, the gpt command can no longer read the GPT on an operating system boot drive, unless System Integrity Protection (SIP) is disabled. The driveinfo command does not require disabling SIP and can produce the same basic tabular output as the gpt command.
