reversing a line

Hi,

I could not find this anywhere and I am wondering if someone knows a quick way of doing this.

So heres the problem... I have a row that looks like this (an example):

5 4 3 2 1

What I want to do is reverse it so it looks like this:

1 2 3 4 5

Does anyone know the simple unix command for this?

thanks
