2
3
4
6 sha512sum - compute and check SHA512 message digest
7
9 sha512sum [OPTION]... [FILE]...
10
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.
