What does "sort -u" do? The man page doesn't make it very clear.

The awk command I inserted simply removes all lines from a file that
are a duplicate of another. Or at least I hope it does - I don't
really know awk but have used this command in a handful of projects
now! So if there are 3 copies of the key in the file, 2 of them will
get removed.
