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.
I pushed a fix at:
https://github.com/coreutils/coreutils/commit/fea833591
Now only the last used --length is validated.
Marking this as done.
cheers,
Pádraig
