The \ is irrelevant! It may be there to indicate that it is part of the same statement (if on two lines).

- The awk '{print $NF}' means print the last field in a space delemmited file.

- Sort -u sort the file, print one recird of each occurence (unique)

- The sed looks likes its trying to replace "." and "$" with nothing.
