Имя (Name)
swaplabel - print or change the label or UUID of a swap area
Синопсис (Synopsis)
swaplabel [-L label] [-U UUID] device
Описание (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 changing the label or UUID on an actively used swap
device.
Параметры (Options)

standard 8-4-4-4-12 character format, such as is output by
