DIGEST determines the digest algorithm and default output format:

• sysv: (equivalent to sum -s)
• bsd: (equivalent to sum -r)
• crc: (equivalent to cksum)
• crc32b: (only available through cksum)
• md5: (equivalent to md5sum)
• sha1: (equivalent to sha1sum)
• sha2: (equivalent to sha{224,256,384,512}sum)
• sha3: (only available through cksum)
• blake2b: (equivalent to b2sum)
• sm3: (only available through cksum)

Examples

Display a 32-bit checksum, size in bytes and filename:
