SWAPLABEL(8) System Administration SWAPLABEL(8)
swaplabel - print or change the label or UUID of a swap area
swaplabel [-L label] [-U UUID] device
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.
-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).
swaplabel was written by Jason Borden <jborden@bluehost.com> and
Karel Zak <kzak@redhat.com>.
LIBBLKID_DEBUG=all
enables libblkid debug output.
The swaplabel command is part of the util-linux package and is
