SWAPLABEL(8)              System Administration             SWAPLABEL(8)

NAME         top

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

SYNOPSIS         top

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

DESCRIPTION         top

       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 changing the label or UUID on an actively used swap
       device.

OPTIONS         top

       -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).

ENVIRONMENT         top

       LIBBLKID_DEBUG=all
           enables libblkid debug output.
