I much prefer using the program `pwgen`. It's installed on all my Linux boxes and it's available from Cygwin too, and it generates a 'pronounceable' password, which makes it a lot easier to remember and also much easier to copy.

There's also the benefit of fewer moving parts -- with a pipeline like that, I'd be worried about accidentally stripping out some of the randomness. I'm fairly confident that a simple invocation of `pwgen` will work.
