Enhancement Request for sha256sum - output only the SHA-256 hash alone

[jens.archlinux jens]

Hello,

propose to add a new option for sha256sum to output only the SHA-256 hash
alone, without a trailing file name and without a trailing newline.

(This would make sense for one input file only).

It would make shell scripts that use sha256sum much simpler. Currently it
is necessary to split the output of sha256sum to obtain the hash, which
usually requires an additional command / Unix process.

Thank you, Jens
