compute and check SHA512 message digest


Calculate the SHA512 checksum for a file

$ sha512sum [path/to/file]

Calculate SHA512 checksums for multiple files
$ sha512sum [path/to/file1] [path/to/file2]

Calculate and save the list of SHA512 checksums to a file
$ sha512sum [path/to/file1] [path/to/file2] > [path/to/file.sha512]

Read a file of SHA512 sums and verify all files have matching checksums
$ sha512sum --check [path/to/file.sha512]

Only show a message for missing files or when verification fails
$ sha512sum --check --quiet [path/to/file.sha512]

Only show a message for files for which verification fails, ignoring missing files
$ sha512sum --ignore-missing --check --quiet [path/to/file.sha512]


sha512sum [OPTION]... [FILE]...


Print or check SHA512 (512-bit) checksums.

With no FILE, or when FILE is -, read standard input.

-b, --binary

read in binary mode

-c, --check

read checksums from the FILEs and check them


create a BSD-style checksum

-t, --text

read in text mode (default)

-z, --zero

end each output line with NUL, not newline, and disable file name escaping

The following five options are useful only when verifying checksums:


don't fail or report status for missing files


don't print OK for each successfully verified file


don't output anything, status code shows success


exit non-zero for improperly formatted checksum lines

-w, --warn

warn about improperly formatted checksum lines


display this help and exit


output version information and exit

The sums are computed as described in FIPS-180-2. When checking, the input should be a former output of this program. The default mode is to print a line with: checksum, a space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant), and name for each FILE.

Note: There is no difference between binary mode and text mode on GNU systems.
