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 ouput by
              uuidgen(1).
