Ubuntu: where are new files installed by using apt-get
 

I use apt-get to install software in Ubuntu 9.04.

However, it does not show where are the new files?

How can I figure out where are those new installed files?

Following is the output, only show it installed, but I want to know what are the new files installed in hard drive, where are they?

Thanks!

Most things get installed to /usr/bin or /usr/sbin. Some main packages get installed to /bin or /sbin.

Or you can see what is in a package by downloading and using apt-file.

I think /usr/lib contains the libraries of the installed packages, while /usr/bin contains the binaries.

Then in /lib and /bin are, respectively, the libraries and binaries of the essential packages for the system to (boot? perform minimally? not sure on this).

The command

dpkg -L <package-name>

will show the files + locations.

This tells you where everything usually goes:

You can also use the apt-file program, which will also show you the files in packages that aren't yet installed.

If you are a newbie, you are probably using Synaptic to install software.
Open synaptic, and go to the settings > preferences menu.
Check the box that says "Show package properties in main window."
Now search for the package that you just installed.
When you select the package, look at the tab called "Installed Files"
By the way, all downloaded packages are stored in /var/cache/apt/archives/
