NAME

sha512sum — write and verify sha512 checksums

SYNOPSIS

sha512sum [-c] [file...]

sha512sum reads each file, or standard input if none were specified, and prints each of their SHA512 checksum.

-c: Verify checksums contained in each file. Currently supported format being checksum, whitespace, an optional asterisk ‘*’ and finally a filename.

The sha512sum utility exits 0 on success, and >0 if an error occurs.

Check tarballs in current directory against the sha512sums.txt digest and ignore the rest of it:

printf %s\n *.tar* | grep -f -
  sha512sums.txt | sha512sum -c -

SHA512 is standardized both in FIPS 180-4 and RFC 6234.
