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  charac-
	      ters, 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).

NAME

       findfs - find a filesystem by label or UUID

SYNOPSIS

       findfs NAME=value

DESCRIPTION

       findfs  will  search the block devices in the system looking for a filesystem or partition with specified tag. The currently supported tags
       are:

       LABEL=<label>
	      Specifies filesystem label.

       UUID=<uuid>
	      Specifies filesystem UUID.

       PARTUUID=<uuid>
	      Specifies partition UUID. This partition identifier is supported for example for GUID  Partition	Table (GPT) partition tables.

       PARTLABEL=<label>
	      Specifies partition label (name). The partition labels are supported for example for GUID Partition Table  (GPT)	or  MAC  partition
	      tables.

       If the filesystem or partition is found, the device name will be printed on stdout.

       The complete overview about filesystems and partitions you can get for example by

	      lsblk --fs

	      partx --show <disk>

	      blkid

EXIT STATUS

	      0      success
	      1      label or uuid cannot be found
	      2      usage error, wrong number of arguments or unknown option
