when i enter terminals commands etc and hit TAB (file name completion) the whole terminal window flashes rapidly (if there is no unique filename for example). This is not good since for some people this can trigger a seizure, and for me it causes really bad headaches. Is there a way we can disable this flashing?

Uncheck the 'visual bell' box in the preferences for your terminal style.

If that's already off, make sure you have disabled System Preferences > Universal Access > Hearing > Flash the screen when an alert sound occurs. – alex Sep 18 '12 at 0:18

This is probably not the right place to ask this question. But there is a setting for that: Settings/Advanced/Visual bell
