'sort' works only when inputs are separated by lines...here they are separated by
spaces.
bash-3.00# echo "hello hello" | sort -u
hello hello

ok, so replace spaces with newLine, sort, and replace newLines with spaces?
How about that?

is that the only way? can't i do it using 'sed' or something?

Don't think you can do with 'sed' only - you can try though.
