Section (8) swaplabel
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 to
change the label or UUID on an actively used swap device.

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).
