For some applications its fairly easy enough to locate where the application was installed to using the "which" command.  However, some applications such as Tomcat are a little out of my league to locate.  I'm asking for particular methodology that can be applied to any apt-get install  to locate where the binary, library, and support files are installed to.  The cause of this question is that I installed Tomcat7 and I can's seem to locate it and I have a list of customizations to perform.

I would like to know what some specific package installs, for example, when installing ncurses, I have found that TAB key expands:  sudo apt-get install ncurses-   to show:  ncurses-base      ncurses-doc       ncurses-hexedit ncurses-bin       ncurses-examples  ncurses-term   How could I know what, say, ncurses-term installs? I am interested mainly in programs, but libraries and any other filetypes could be useful too.  Command-line method, if possible, would be preferred (any others accepted too).

Simple enough question: is there some shell command (or GUI method) I can use that, given the path to a file on my system, tells me what package put it there? Assuming the file did in fact come from a package, that is.  Bonus question: what if it's a file that isn't installed on my system? Is there, say, a website that will let me look up a file and see what packages, if any, provide it?

Background: I'm trying to build my program but first I need to set up libraries in netbeans. My project is using GLU and therefore I installed libglu-dev. I didn't note location where the libraries were located and now I can't find them..  I've switched to Linux just a few days ago and so far I'm very content with it, however I couldn't google this one out and becoming frustrated.. Is there way to find out where files of package were installed without running installation again? I mean if I got library xxx and installed it some time ago, is there somecommand xxx that will print this info?  I've already tried locate, find and whereis commands but either I'm missing something or I just can't do it correctly.. for libglu, locate returns:  /usr/share/bug/libglu1-mesa /usr/share/bug/libglu1-mesa/control /usr/share/bug/libglu1-mesa/script /usr/share/doc/libglu1-mesa /usr/share/doc/libglu1-mesa/changelog.Debian.gz /usr/share/doc/libglu1-mesa/copyright /usr/share/lintian/overrides/libglu1-mesa /var/lib/dpkg/info/libglu1-mesa:i386.list /var/lib/dpkg/info/libglu1-mesa:i386.md5sums /var/lib/dpkg/info/libglu1-mesa:i386.postinst /var/lib/dpkg/info/libglu1-mesa:i386.postrm /var/lib/dpkg/info/libglu1-mesa:i386.shlibs   Other two commands fail to find anything. Now locate did it's job but I'm sure none of those paths is where the library actually resides (at least everything I was linking so far was in /usr/lib or usr/local/lib).   The libglu was introduced just as example, I'm looking for general solution for this problem.
