swaplabel - print or change the label or UUID of a swap area


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


   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

   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.
