NAME

6       swaplabel - Print or change the label / UUID of a swap area
7

SYNOPSIS

9       swaplabel [-L label] [-U UUID] device
10

DESCRIPTION

12       swaplabel  will  display or change the label / UUID of a swap partition
13       located on device (or regular file).
14
15       If the optional arguments -L and -U are  not  present,  swaplabel  will
16       simply display the swap area label and UUID of device.
17
18       If  an  optional  argument  is  present, then swaplabel will change the
19       appropriate value of device.  These values can also be set during  swap
20       creation  using  mkswap(8).  The swaplabel utility allows to change the
21       label or UUID on actively used swap device.
