NAME

6       sha512sum - compute and check SHA512 message digest

SYNOPSIS

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

DESCRIPTION

12       Print  or check SHA512 (512-bit) checksums.  With no FILE, or when FILE
13       is -, read standard input.
14
15       -b, --binary
16              read in binary mode
17
18       -c, --check
19              read SHA512 sums from the FILEs and check them
20
21       -t, --text
22              read in text mode (default)
23
24              Note: There is no difference between binary and text mode option
25              on GNU system.
26
27   The following three options are useful only when verifying checksums:
28       --quiet
29              don't print OK for each successfully verified file
30
31       --status
32              don't output anything, status code shows success
33
34       -w, --warn
35              warn about improperly formatted checksum lines
36
37       --help display this help and exit
38
39       --version
40              output version information and exit
41
42       The  sums  are computed as described in FIPS-180-2.  When checking, the
43       input should be a former output of this program.  The default  mode  is
44       to  print  a  line  with checksum, a character indicating type (`*' for
45       binary, ` ' for text), and name for each FILE.
