Thanks for Help on Bash/BC

Hard to imagine but much of my time at HP was spent maintaining a 6000 line csh script.  Eventually I refactoring it into three sorta maintainable almost comprehensible scripts.  It was an elaborate system for doing smoke test of firmware before loading it into a printer.  Like it sounds, I am sure it made sense at 200 lines but someone just could not stop before the csh dragon carried them away.
