<B>swaplabel</B>
|
|
|
|
will display or change the label or UUID of a swap partition located on

<I>device</I>
|
|
|
|
(or regular file).
|

If the optional arguments
|
|
<B>-L</B>
|
|
|
|
and
|
|
<B>-U</B>
|
|
|
|
are not given,
|
|
<B>swaplabel</B>
|
|
|
|
will simply display the current swap-area label and UUID of
|
|
<I>device</I>.
|
|
|
|
<P>
|
|
|
|
If an optional argument is present, then
|
|
<B>swaplabel</B>
|
|
|
|
will change the appropriate value on
|
|
<I>device</I>.
|
|
|
|
These values can also be set during swap creation using
|
|
<B><A HREF="/cgi-bin/man/man2html?8+mkswap">mkswap</A></B>(8).
|
|
|
|
The
|
|
<B>swaplabel</B>
|
|
|
|
utility allows to change the label or UUID on an actively used swap device.
