SWAPLABEL(8)		   Linux Programmer's Manual		  SWAPLABEL(8)

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

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

DESCRIPTION
       swaplabel  will	display or change the label / UUID of a swap partition
       located on device (or regular file).

       If the optional arguments -L and -U are	not  present,  swaplabel  will
       simply display the swap area label and UUID of device.

       If  an  optional	 argument  is  present, then swaplabel will change the
       appropriate value of device.  These values can also be set during  swap
       creation	 using	mkswap(8).  The swaplabel utility allows to change the
       label or UUID on actively used swap device.

OPTIONS
       -h, --help
	      Print help and exit.

       -L, --label label
	      Specify a new label for device.  Swap partition labels can be at
	      most 16 characters long.	If label is longer than 16 characters,
	      swapinfo will truncate it and print a warning message.

       -U, --uuid uuid
	      Specify a new UUID for device.  UUID must	 be  in	 the  standard
	      8-4-4-4-12 character format, such as is output by uuidgen(1).
