NAME

6       sha512sum - compute and check SHA512 message digest

SYNOPSIS

9       sha512sum [OPTION]... [FILE]...
10

DESCRIPTION

12       Print or check SHA512 (512-bit) checksums.
13
14       With no FILE, or when FILE is -, read standard input.
15
16       -b, --binary
17              read in binary mode
18
19       -c, --check
20              read SHA512 sums from the FILEs and check them
21
22       --tag  create a BSD-style checksum
23
24       -t, --text
25              read in text mode (default)
26
27       -z, --zero
28              end  each  output  line  with NUL, not newline, and disable file
29              name escaping
30
31   The following five options are useful only when verifying checksums:
32       --ignore-missing
33              don't fail or report status for missing files
34
35       --quiet
36              don't print OK for each successfully verified file
37
38       --status
39              don't output anything, status code shows success
40
41       --strict
42              exit non-zero for improperly formatted checksum lines
43
44       -w, --warn
45              warn about improperly formatted checksum lines
46
47       --help display this help and exit
48
49       --version
50              output version information and exit
51
52       The sums are computed as described in FIPS-180-2.  When  checking,  the
53       input  should  be a former output of this program.  The default mode is
54       to print a line with checksum, a space, a  character  indicating  input
55       mode  ('*'  for binary, ' ' for text or where binary is insignificant),
56       and name for each FILE.
57
58       Note: There is no difference between binary mode and text mode  on  GNU
59       systems.
