I found the problem. I really, really hope someone can explain it. The top line does not work. The bottom one does. I manually typed the top line in. I copied and pasted the bottom line from the scripts supplied with the book. The quote marks look different. What in the world is going on here? I'm doing this on KDE Neon and in vim.

I think you have that backwards. The top line should work; the bottom line can't work. The shell command language has rules for constructing commands just like English has rules for constructing sentences. In English, sentences are terminated by a period, a question mark, or an exclamation point. The following is not an English sentence, because a semicolon is not a period, is not a question mark, and is not an exclamation point.
In the shell command language quoted strings are surrounded by double-quote characters (") or single-quote characters ('). And, the opening-double-quote character (“) and closing-double-quote character (”) is not a double-quote character (although in some fonts they look similar). Instead of being characters delimiting a double-quoted string, they are regular characters that are part of an unquoted string (or if there are whitespace characters between those quotes, part of multiple unquoted strings).
The top line has the normal ASCII quotes.
They work in the sense "protect the variable from splitting and globbing".
But in this case a splitting is wanted (as I said in post #7).
The "wrong" (alternate?) quotes in the second line might, after splitting into words, be added at the beginning of the first word and at the end of the last word. So might also spoil it, in this case the first and last path element.
