# cryptsetup-luksUUID(8)

print or set the UUID of a LUKS device

## 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.*

## REPORTING BUGS

*Report bugs at* *cryptsetup mailing list \<cryptsetup@lists.linux.dev\>* *or in* *Issues project section \<https://gitlab.com/cryptsetup/cryptsetup/-/issues/new\>.*

*Please attach the output of the failed command with --debug option added.*
