label (command)

In computing, label is a command included with some operating systems (e.g., DOS,^[1] OS/2 and Microsoft Windows^[2]). It is used to create, change, or delete a volume label on a logical drive, such as a hard disk partition or a floppy disk. Used without parameters, label changes the current volume label or deletes the existing label.

In Unix and other Unix-like operating systems, the name of the equivalent command differs from file system to file system. For instance, the command e2label can be used for ext2 partitions.

Syntax

LABEL [/MP] [volume] [label]

Arguments:

drive: This command-line argument specifies the drive letter of a drive.
label Specifies the label of the volume.
volume Specifies the drive letter (followed by a colon), mount point, or volume name.

Flags:

Note: If volume name is specified, the /MP flag is unnecessary.
