NAME         top

       cryptsetup-isLuks - check if a device is a LUKS device

SYNOPSIS         top

       cryptsetup isLuks [<options>] <device>

DESCRIPTION         top

       Returns true, if <device> is a LUKS device, false otherwise.

       Use option -v to get human-readable feedback. 'Command
       successful.' means the device is a LUKS device.

       By specifying --type you may query for specific LUKS version.

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

OPTIONS         top

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

       --usage
           Show short option help.

       --verbose, -v
           Print more information on command execution.

       --version, -V
           Show the program version.
