sha256sum

Calculate hash for each input file, reading from stdin if none, writing hexadecimal digits to stdout for each input file (md5=32 hex digits, sha1=40, sha224=56, sha256=64, sha384=96, sha512=128) followed by filename. toybox

-bBrief (hash only, no filename)
-cCheck each line of each FILE is the same hash+filename we'd output
-sNo output, exit status 0 if all hashes match, 1 otherwise

Calculate SHA256 cryptographic checksums.

Calculate the SHA256 checksum for one or more files

sha256sum path/to/file1 path/to/file2 ...Identify

Calculate and save the list of SHA256 checksums to a file

sha256sum path/to/file1 path/to/file2 ... >path/to/file.sha256Identify

Calculate a SHA256 checksum from stdin

command | sha256sumIdentify

Read a file of SHA256 checksums and filenames and verify all files have matching checksums

sha256sum --check path/to/file.sha256Identify

Only show a message for missing files or when verification fails

sha256sum --check --quiet path/to/file.sha256Identify

Only show a message when verification fails, ignoring missing files

sha256sum --ignore-missing --check --quiet path/to/file.sha256Identify

Check a known SHA256 checksum of a file

echo known_sha256_checksum_of_the_file path/to/file | sha256sum --checkIdentify
