Where are my installed applications?

  • I have installed Skype in Ubuntu, but I do not know where to start the installed the Skype application .Similarly I have installed Netbeans and other applications but their icons are not appearing in any menus.

    Related: how to uninstall already installed applications?

    So how do I find the answers?

  • The executables are located in the /usr/bin folder. I guess pressing Alt+F2 and typing

    skype
    

    will do. It might also fall under the Applications menu > Internet.

    To uninstall already installed software, you can:

    1. Go to Software-center. Find the software and remove.
    2. Open a terminal, and type

      sudo apt-get remove <software-name>
      

    If you do not know the complete name, just type a few characters of the application, and press tab twice. That will auto complete, or show a list of matching applications.

    You don't need the whole path when using Alt+F2 (or the terminal or desktop/panel shortcuts). Just typing `skype` will suffice.

    Oops, overlooked that! Thanks for the heads-up. But there was a time that I had to give the entire path. Dont remember the applicaton now.

    You have to give the full path if you don't install it "properly"...

    you can find local software in /usr/local also.

    Where is installed application's folder?! For example tomcat7 folder.

  • You can discover where a package puts its 'stuff' by running:

    dpkg -L 'packagename'
    

    There's still a set of 'standard' locations that programs are put into. For example, binaries (in windows parlance 'executables') are put in /usr/bin, and documentation is put in /usr/share/doc in a Ubuntu system.

    This is a pretty simplistic answer. For more details about how linux/unix directories are typically structured, see this:

    http://www.pathname.com/fhs/pub/fhs-2.3.html

    When I try the dpkg example, I get "dpkg-query: package 'packagename' is not installed"

  • There are some very good answers to a similar question to yours over at

    What is the Linux equivalent to Windows' Program Files?

    But the general idea is that the /bin and /usr/bin are where the start up application files (executables or scripts) are stored. The direct equivalent of "Program Files" though is probably /usr/share this is the directory that contains the various support files for most applications

    For a good overview of the Ubuntu file structure check out the link below.

    https://help.ubuntu.com/community/LinuxFilesystemTreeOverview

    Many of the files in `/bin` and `/usr/bin` are scripts, but more are actual binary executables.

  • There is no "Program Files" Directory in Linux. The Application's Parts are distributed according to what they are. There are a lot of explanations of the Directory Structure out there, you can use this one for a start.
