# cryptsetup-luksUUID

## NAME



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


## SYNOPSIS



           **cryptsetup** _luksUUID_ **[ <options>] <device>**
    


## DESCRIPTION



           Print the UUID of a LUKS device.
    
           Set new UUID if --uuid option is specified.
    
           **< options> **can be [--header, --uuid, --type, --disable-locks].
    


## OPTIONS



           **--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.
    
           **--disable-locks**
               Disable lock protection for metadata on disk. This option is
               valid only for LUKS2 and is 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).
    
           **--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 the
               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.
    
           **--help** , **-?**
               Show help text and default parameters.
    
           **--type** _type_
               Specifies required device type, for more info, read the _BASIC_
               _ACTIONS_ section in cryptsetup(8).
    
           **--usage**
               Show short option help.
    
           **--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.
    
           **--version** , **-V**
               Show the program version.
