For some time I had in mind option to hash-sum that would only print
checksum without filename as it is very useful when using calculated

external command like awk, I decided to add something simple to
hash-sum command/s. I was intending to name it `-1' but found
out that BSD already have[1] exactly that option and use `quiet'
(`-q' for short) switch. So I followed suit and utilised already
existing `--quiet' option. Attached short diff/patch for that
occasion. How you find it useful and worth implementing. Regards

Piotr Dabrowski asked this recently, and my response then was:
"Using the --quiet option for this seems a little awkward.
One reason we added the --raw option, was for this single input case.
I.e. please consider using something like this example:"
cksum --raw -a md5 | basenc --base16
Now the BSDs implementing -q for this does change things a bit,
as we'd be adding compat, albeit without adding functionality.
So given there are two separate suggestions for this and
we're increasing compat, I'm 55:45 for adding this now.
Note FreeBSD at least will output checksums without file name
for all specified files, though that would be an unusual use case.
I'm unsure of which command hash-sum is, but I note that toybox has been
using -b (brief) in md5sum through sha3sum for 10 years now:
https://github.com/landley/toybox/commit/2682551a4b19
Which isn't just android, QNX 8 switched to toybox, and I'm happy to
poke the busybox guys..

(And yes I went with -b because "quiet" already had a different meaning.)
I'd probably have poked you guys about -b earlier but it's been 6 months
since https://lists.gnu.org/archive/html/coreutils/2024-06/msg00017.html
which didn't get a reply, but
https://lists.gnu.org/archive/html/coreutils/2023-08/msg00039.html did...
