NAME¶
swaplabel - print or change the label or UUID of a swap area
SYNOPSIS¶
swaplabel [
-L label] [
-U UUID]
device
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 to change
the label or UUID on an actively used swap device.
OPTIONS¶
- -h, --help
- Display help text and exit.
- -L, --label label
- 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.
- -U, --uuid UUID
- 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).
