Use grep and sed/awk
grep -e '80/open/tcp' infile | awk '{print $2}' | sort -u > outfile

Clojure uses java classes instead of introducing its own type system... .
Typically type questions in Clojure come down to asking "what class is this, or what primitive-wrapper-class can contain it." This comes from Clojure's first class treatment of java .
