I'm going to presume that you want to search for a
specific set of numbers, and that the fact that the
fact that they're odd doesn't matter....

In that case, you'd have to use a for loop to seach
thru the list of 'important' values:

for $tval in 1 3 5 7 9; do
	if [ $a -eq $tval ]
	  then
		echo -n "$a "
	fi
done

As far as I know, there's no fast way to search for
one value in a list of candidates.
