The man page for pw says that pw needs a file descriptor to set the
password via -h

I'm not 100% sure, but I seem to remember that most shells provide a
sort of "heredoc" support for this.  Such that:

pw usermod "$user" -h <<<END
newpassword
newpassword
END

would work.  Don't quote me on this.  I'm sure of the basic approach,
but I'm not sure of the exact syntax used.  I just had a thought,
though - the version of the adduser script in FreeBSD 5 is written
in sh instead of perl (4.x is in perl) so you should be able to check
that code for a workable syntax.
