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.

           be at most 16 characters long. If label is longer than 16
           characters, swaplabel will truncate it and print a warning
           message.
