The title of this question pretty much says it all. What command or program do I need to run in order to change the clock speed to a specific value I want? For example, I'm looking for something like <command name> 1.7, or something similar, to change the speed to a specified frequency in GHz or MHz. I would prefer a terminal application, but a desktop app would also suffice.

I am using Ubuntu 12.04 LTS.
