swaplabel
SWAPLABEL(8) System Administration SWAPLABEL(8)
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 charac-
ters, 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).
AUTHOR
swaplabel was written by Jason Borden <jborden@bluehost.com> and Karel Zak <kzak@redhat.com>.
ENVIRONMENT
LIBBLKID_DEBUG=0xffff
enables debug output.
AVAILABILITY
The swaplabel command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
