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,
−−helpDisplay help text and exit.
−L,
−−label labelSpecify 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 UUIDSpecify 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).
