NAME

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

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 simply 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 characters, 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 uuidgen(1).
