       -a, --algorithm=KI<?>U
              select the digest type to use.  See DIGEST below

       --base64
              emit base64-encoded digests, not hexadecimal

       -c, --check
              read checksums from the FILEs and check them

       -l, --length=BITS
              digest length in bits; must not exceed the max size and must be
              a multiple of 8 for blake2b; must be 224, 256, 384, or 512 for
              sha2 or sha3

       --raw  emit a raw binary digest, not hexadecimal

       --tag  create a BSD-style checksum (the default)

       --untagged
              create a reversed style checksum, without digest type

   DIGEST determines the digest algorithm and default output format:
       sysv   (tuong duong v<?>i "sum -s")

       bsd    (tuong duong v<?>i "sum -r")

       crc    (tuong duong v<?>i "cksum")

       crc32b (only available through cksum)

       md5    (tuong duong v<?>i "md5sum")

       sha1   (tuong duong v<?>i "sha1sum")

       sha2   (tuong duong v<?>i "sha{224,256,384,512}sum")

       sha3   (only available through cksum)

       blake2b
              (tuong duong v<?>i "b2sum")

       sm3    (only available through cksum)

       When checking, the input should be a former output of this program, or
       equivalent standalone program.
