And finally, why don't you just use grep? At least with your trivial example, it is significantly faster.

You are comparing apples to oranges.

grep is always O( N ) and will work whether the data is sorted or not.

Binary Search has a best case of O( 1 ) and a worst case of O( log N ) and will only work if the data is sorted.
