Vol (command)

In some operating systems,   is a command within the command-line interpreters (shells) such as  and. It is used to display the volume label and volume serial number of a logical drive, such as a hard disk partition or a floppy disk, if they exist.

Implementations
The command is available in various versions of DOS, DR FlexOS, IBM/Toshiba 4690 OS, IBM OS/2, Microsoft Windows, and ReactOS.

On MS-DOS, the command is available in versions 2 and later. Paragon Technology Systems PTS-DOS 2000 Pro also includes a vol implementation.

The Windows  command also displays the volume label and serial number (if it has one) as part of the directory listing.

The command is also available in the EFI shell.
