4.16 Mlabel

The mlabel command adds a volume label to a disk. Its syntax is:

mlabel [-vcsn] [-N serial] drive:[new_label]

Mlabel displays the current volume label, if present. If new_label is not given, and if neither the c nor the s options are set, it prompts the user for a new volume label. To delete an existing volume label, press return at the prompt.

The label is limited to 11 single-byte characters, e.g. Name1234567.

Reasonable care is taken to create a valid MS-DOS volume label. If an invalid label is specified, mlabel changes the label (and displays the new label if the verbose mode is set). Mlabel returns 0 on success or 1 on failure.

Mlabel supports the following options:

c

Clears an existing label, without prompting the user

s

Shows the existing label, without prompting the user.

n

Assigns a new (random) serial number to the disk

N serial

Sets the supplied serial number. The serial number should be supplied as an 8 digit hexadecimal number, without spaces
