${NFN// /-} uses "parameter expansion: pattern substitution" to replace all spaces in a string with dashes. You could try to apply it repeatedly to reduce / remove the multiple space occurrences.
See e.g. man bash for reference of the two builtins.

Although man-pages is the place where I always get lost you gave me the secret word: "parameter expansion" so now I can Google it instead finding examples!
