No script output to stdout,stderr

[Brendan Gibson]

Yes they do.  Only when a shell script is called with #! in the top of an
external file do I get no output.  I have been able to work around it, but
still puzzles me.

No, I don't know what's going on. It is not normal at all.
Do other commands produce output in that shell?
