NAME
swaplabel - print or change the label or UUID of a swap area
SYNOPSIS
swaplabel
[
-L
label]
[
-U
UUID]
device
DESCRIPTION
swaplabel
will display or change the label or UUID of a swap partition located on
device
(or regular file).
If the optional arguments
-L
and
-U
are not given,
swaplabel
will simply display the current swap-area label and UUID of
device.
If an optional argument is present, then
swaplabel
will change the appropriate value on
device.
These values can also be set during swap creation using
mkswap(8).
The
swaplabel
utility allows changing the label or UUID on an actively used swap device.
OPTIONS
- -h, --help
-

- -L, --label label

label
is longer than 16 characters,
swaplabel
will truncate it and print a warning message.
- -U, --uuid UUID
-
Specify a new UUID for the device.
The UUID
must be in the standard 8-4-4-4-12 character format, such as is output by
uuidgen(1).
