shasum
Calculate SHA cryptographic checksums. More information: https://manned.org/shasum.
- Calculate the SHA1 checksum for one or more files:
shasum
path/to/file1 path/to/file2 …
- Calculate the SHA checksum for one or more files with the specified algorithm:
shasum --algorithm
1|224|256|384|512|512224|512256
path/to/file1 path/to/file2 …
- Calculate a SHA1 checksum from
stdin
:
command | shasum
- Calculate and save the list of SHA256 checksums to a file:
shasum --algorithm 256
path/to/file1 path/to/file2 … >
path/to/file.sha256
- Read a file of SHA checksums and filenames and verify all files have matching checksums (the algorithm will be automatically detected):
shasum --check
path/to/file
- Only show a message for missing files or when verification fails:
shasum --check --quiet
path/to/file
- Only show a message when verification fails, ignoring missing files:
shasum --ignore-missing --check --quiet
path/to/file
- Check a known SHA checksum of a file:
echo
known_sha_checksum_of_the_file
path/to/file | shasum --check
