- --untagged
-
create a reversed style checksum, without digest type
- --tag
-
create a BSD style checksum (default)
- -l, --length
-
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
- -c, --check
-
read checksums from the FILEs and check them
- -w, --warn
-
warn about improperly formatted checksum lines
- --status
-
don't output anything, status code shows success

-
don't print OK for each successfully verified file
- --ignore-missing
-
don't fail or report status for missing files
- --strict
-
exit non-zero for improperly formatted checksum lines
- --base64
-
emit base64-encoded digests, not hexadecimal
- -z, --zero
-
end each output line with NUL, not newline, and disable file name escaping
- --debug
-
print CPU hardware capability detection info used by cksum
- -h, --help
-
Print help
- -V, --version
-
Print version
EXTRA
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
