shasum

all

Calculate SHA cryptographic checksums.

Options (1)

-c, --checkboolean

Read a file of SHA checksums and filenames and verify all files have matching checksums (the algorithm will be automatically detected)

Example: shasum {{[-c|--check]}} {{path/to/file}}

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 [-c|--check] path/to/file

Only show a message for missing files or when verification fails

shasum [-c|--check] --quiet path/to/file

Only show a message when verification fails, ignoring missing files

shasum --ignore-missing [-c|--check] --quiet path/to/file

Check a known SHA checksum of a file

echo known_sha_checksum_of_the_file path/to/file | shasum [-c|--check]
