# sha512sum
# Calculate SHA512 cryptographic checksums.
# More information: <https://www.gnu.org/software/coreutils/manual/html_node/sha2-utilities.html>.
# 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
