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 SHA256 checksum for one or more files:
  shasum --algorithm 256 {{path/to/file1 path/to/file2 ...}}
• Calculate the SHA512 checksum for one or more files:
  shasum --algorithm 512 {{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 SHA1 sums and filenames and verify all files have matching checksums:
  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}}
