Where is Ubuntu storing installed programs?
ubuntu, ubuntu-10.04, ubuntu-11.04
Solution
If you installed the package with the Ubuntu package manager (apt, synaptic, dpkg or similar), you can get information about the installed package with
dpkg -L <package_name>
Problem
I am using Ubuntu and when I click on a program to download Firefox asks me "What should firefox do with this file?" And in the "Open with" I would like to find a program "Package installer". The problem is - I don't know where to look for. Where is the program stored (I installed it using Ubuntu Software Center)
