NAME

6       cryptsetup-isLuks - check if a device is a LUKS device
7

SYNOPSIS

9       cryptsetup isLuks [<options>] <device>
10

DESCRIPTION

12       Returns true, if <device> is a LUKS device, false otherwise.
13
14       Use option -v to get human-readable feedback. 'Command successful.'
15       means the device is a LUKS device.
16
17       By specifying --type you may query for specific LUKS version.
18
19       <options> can be [--header, --type, --disable-locks].
20

OPTIONS

22       --verbose, -v
23           Print more information on command execution.
24
25       --type <device-type>
26           Specifies required device type, for more info read BASIC ACTIONS
27           section in cryptsetup(8).
28
29       --header <device or file storing the LUKS header>
30           Use a detached (separated) metadata device or file where the LUKS
31           header is stored. This option allows one to store ciphertext and
32           LUKS header on different devices.
33
34           For commands that change the LUKS header (e.g. luksAddKey), specify
35           the device or file with the LUKS header directly as the LUKS
36           device.
37
38       --disable-locks
39           Disable lock protection for metadata on disk. This option is valid
40           only for LUKS2 and ignored for other formats.
41
42           WARNING: Do not use this option unless you run cryptsetup in a
43           restricted environment where locking is impossible to perform
44           (where /run directory cannot be used).
45
46       --batch-mode, -q
47           Suppresses all confirmation questions. Use with care!
48
49           If the --verify-passphrase option is not specified, this option
50           also switches off the passphrase verification.
51
52       --debug or --debug-json
53           Run in debug mode with full diagnostic logs. Debug output lines are
54           always prefixed by #.
55
56           If --debug-json is used, additional LUKS2 JSON data structures are
57           printed.
58
59       --version, -V
60           Show the program version.
61
62       --usage
63           Show short option help.
64
65       --help, -?
66           Show help text and default parameters.
67
