Hi, When specifying an invalid length value followed by a valid length value I get the following error:
$ printf "hello" | cksum --algo=blake2b --length=12 --length=8 cksum: invalid length: ‘12’ cksum: length is not a multiple of 8 However, if the invalid length value is a multiple of 8 and greater than 512 (the maximum digest length for blake2b), there is no error: $ printf "hello" | cksum --algo=blake2b --length=123456 --length=8 BLAKE2b-8 (-) = 29 I think the behavior should be the same in the two scenarios, whether it's showing an error or ignoring the invalid value. I'm using coreutils 9.4. Regards, Daniel
