`sha256sum --help` does not document the `-b` option

[app20200]

Description

sha256sum appears to support the -b option, but the option is not documented in the --help output.

If the -b option is intentionally supported, could you please add it to the help message?

Steps to Reproduce

C:\Temp>sha256sum --version
sha256sum (uutils coreutils) 0.8.0

C:\Temp>sha256sum --help
Print or check the SHA256 checksums

Usage: sha256sum [OPTIONS] [FILE]...

Options:
  -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
      --quiet           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
      --tag             create a BSD style checksum
  -t, --text            read in text mode (default)
  -z, --zero            end each output line with NUL, not newline, and disable file name escaping
  -h, --help            Print help
  -V, --version         Print version

The -b option is not listed in the output above, although it appears to be supported by sha256sum.

Expected Behavior

If -b is a supported option, sha256sum --help should document it and describe its behavior.

Environment

• OS: Windows 11 25H2
• sha256sum: uutils coreutils 0.8.0 (Servicing Release 2026.6.16)

This is an upstream issue, common to all platforms. Do you mind reporting this here? https://github.com/uutils/coreutils

Thank you for the clarification.
I’ll take a look at the latest uutils/coreutils release first, since it provides a newer Windows x64 version.
