15 swaplabel - print or change the label or UUID of a swap area
19 *swaplabel* [*-L* _label_] [*-U* _UUID_] _device_
23 *swaplabel* will display or change the label or UUID of a swap partition located on _device_ (or regular file).
25 If the optional arguments *-L* and *-U* are not given, *swaplabel* will simply display the current swap-area label and UUID of _device_.
27 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.
31 include::man-common/help-version.adoc[]
33 *-L*, *--label* _label_::
34 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.
36 *-U*, *--uuid* _UUID_::
37 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).
42 enables libblkid debug output.
