Hi,

I want to read a file, and write to another file by randomize the lines.  
I saw the method File.lineno= but it doesn’t seem to work. I just get  
the same file written as the original, without the lines having been  
randomized.

I suppose it should be simple, but am new to Ruby. Any help would be  
great.

Thanks,

Asitya
