If you're referring to the space and then the file name ("-" in case
of stdin) on the end, you can just select only the first output up
to whitespace with e.g. awk:

    _SHA256=$(printf '%s' "${_TXT}" | sha256sum | awk '{print $1}')

Your use of "--text" does nothing by the way.

These web sites can change their URLs at any time you know, so it
may not be worth trying to replicate their structure locally.

Also maybe you want some sort of web site mirroring solution.
