I need to remove Pitivi video editor and Cinelerra and a few more applications, I have seen people talking about how to uninstall something completely but the problem is that I don't even know the "name" of my applications. When I say "name", I mean the name that I could put in the terminal to run/install/remove them. Please help me, my computer is running out of disk space.

You could use apt-cache search KEYWORDS to search for the package name which contains KEYWORDS in its description.

You can also use dpkg -l PACKAGENAME to list all installed packages that match the pattern PACKAGENAME. You can use ? (one arbitrary character) and * (any number of arbitrary characters) as wildcards.

Then use sudo apt-get autoremove --purge PACKAGE to remove PACKAGE completely, including configuration and all no longer needed dependencies.

Example for PiTiVi:

  • Find out the package name:

    $ apt-cache search PiTiVi
    pitivi - non-linear audio/video editor using GStreamer
    
  • Purge the package and its dependencies:

    $ sudo apt-get autoremove --purge pitivi
    [...some output...]
    
  • Ok thanks! And by the way do you know what happened to my minecraft? I can't do anything on servers I used to use java 7 now I switched to java 8 and a lot of things go wrong in singleplayer but in multiplayer things go better :/ – Emily Shan Jan 4 '16 at 22:26
  • @EmilyShan Sorry, but I don't use Minecraft, so I can't help you there. However I think I've heard that they recommend the Oracle implementation and not the OpenJDK implementation. Maybe that makes a difference... But you should ask a new question about that issue, nobody will notice it if you place it in a comment here.

  • Oh ok, it's all right. And by the way, what is the difference between the up arrow and the check? I always forget it sorry. And thanks a lot for the commands they worked!{for me, since I'm horrible with computers, almost nothing works(Idk how to use them)} – Emily Shan Jan 18 '16 at 2:15
  • By the way, for cinelerra, how do I find out the package name? When I go to applications then sound and videos then it says Cinelerra-CV, when I put "apt-cache search cinelerra-cv" it says "cinelerra-cv - Non-linear audio/video authoring tool" – Emily Shan Jan 18 '16 at 2:20
  • You can also use dpkg -l PACKAGENAME to list all installed packages that match the pattern PACKAGENAME. You can use ? (one arbitrary character) and * (any number of arbitrary characters) as wildcards. In your case, I would try e.g. dpkg -l cine* or dpkg -l cinelerra*. – Byte Commander Jan 18 '16 at 7:21
