swaplabel


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  sim-
       ply 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.

OPTIONS
       -h, --help
              Display help text and exit.

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

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