Request for option to print/return only the hash value

[rhash]

Discussed in #217

As title, would like an even simpler version of the --simple output format option, where only the actual hash value is returned - no filename or other information.

I think good name for the command line option would be one of: --no-filename, --no-path, --only-hash.

For quick workarround see @greisch answer in #217.

[rhash]

Supported by f405c3a.
Now formatting option --one-hash prints the selected hash and new line (LF symbol):

$ rhash --one-hash --md5 --message "abc"

The feature is included into RHash v1.4.5.
