A good solution. Thank NC.
The only thing I can see that if 3663782 is exactly the size of your text
file sometimes your script will produce nothing. It will happen when
rand returns a big number, close to 3663782 enough to fall into the very
last line and then behind it on the second fgets().
So reduce that number by the length of the last line... if you didn't yet,
of course.
