NAME         top

       cryptsetup-luksUUID - print or set the UUID of a LUKS device

SYNOPSIS         top

       cryptsetup luksUUID [<options>] <device>

DESCRIPTION         top

       Print the UUID of a LUKS device.
       Set new UUID if --uuid option is specified.

       <options> can be [--header, --uuid, --type, --disable-locks].

OPTIONS         top

       --type <device-type>
           Specifies required device type, for more info read BASIC
           ACTIONS section in cryptsetup(8).

       --uuid <UUID>
           Use the provided UUID for the luksFormat command instead of
           generating a new one. Changes the existing UUID when used
           with the luksUUID command.

           The UUID must be provided in the standard UUID format, e.g.
           12345678-1234-1234-1234-123456789abc.

       --header <device or file storing the LUKS header>
           Use a detached (separated) metadata device or file where the
           LUKS header is stored. This option allows one to store
           ciphertext and LUKS header on different devices.

           For commands that change the LUKS header (e.g. luksAddKey),
           specify the device or file with the LUKS header directly as
           the LUKS device.

       --disable-locks
           Disable lock protection for metadata on disk. This option is
           valid only for LUKS2 and ignored for other formats.

           WARNING: Do not use this option unless you run cryptsetup in
           a restricted environment where locking is impossible to
           perform (where /run directory cannot be used).

       --batch-mode, -q
           Suppresses all confirmation questions. Use with care!

           If the --verify-passphrase option is not specified, this
           option also switches off the passphrase verification.

       --debug or --debug-json
           Run in debug mode with full diagnostic logs. Debug output
           lines are always prefixed by #.

           If --debug-json is used, additional LUKS2 JSON data
           structures are printed.

       --version, -V
           Show the program version.

       --usage
           Show short option help.

       --help, -?
           Show help text and default parameters.
