super quick and dirty way is use the space as your seperator and load each element into a hash.

hashes can only contain unique keys. so if you load up a hash then you are sure to get no duplicates.

then you just spit out each key and reform your line.

Try...

tr ' ' '\012' < test.txt | sort -u | paste -s -d' ' - > outfile
