QuickPI is a Windows only command line tool that will generate pi to arbitrary length up to 256 million decimal places. It will optionally write this output to a text file.
By entering this command:
qpi 1mi -fancy:100,100,1000000,,no, pi.txt
I was able to generate the following output:

There is a wealth of other utilities to calculate pi available here.
The differ in their supported:
- platforms (mainly Windows and Linux binaries, some source)
- maximum decimal places (PiFast claims 12 billion)
- performance characteristics
Not having used any of these other utilities I am unable to comment on individual features.
pi
? Is the point to generate or use those?
