Where are application files on Ubuntu Linux?
I’m trying to direct thunderbird to my browser’s application file so it knows what program to use to open links. Where should I look for the file that runs – say, for example – Chromium? Firefox (Shiretoko on 64 bit systems)?
I’m running 64 bit Ubuntu Linux 9.10.
