swaplabel

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).
