I have deinstalled a package (epiphany) which showed up thrice in the dash. Now, one of the application-icons is gone, yet two remain.

I want to know where to start looking into this problem: how does the Dash application-lense determine its contents? And where (if at all) is that saved or cached?

lsof -c unity and the likes, may list the file(s) or folder I am looking for, but wading through all that content is just too much work :)

sure. If you tell me what to grep for :) (which is, the name of the dir, file or cache that contains the entries) –  berkes Apr 4 '13 at 8:27
    
Try ls /usr/share/applications | grep epiphany. –  mikewhatever Apr 4 '13 at 9:23
    
/usr/share/applications does not contain anything referring to epiphany (I grepped all content), nor does /usr/share/application-registry. I suspect these entries lie below my $HOME. –  berkes Apr 4 '13 at 10:17
    
what about ~/.local/share/applications? –  user25656 Apr 4 '13 at 12:45

Application launchers - or rather their respective .desktop files - are stored under these directories:

  • /usr/share/applications - all users

  • $HOME/.local/share/applications - your user

If you look through these you should be able to find the culprit.


Another option are GUI menu editors. Out of the ones available I prefer MenuLibre, a pretty new project originally coded for the Ubuntu App Showdown. You can install the latest release from the developer's PPA by typing:

sudo add-apt-repository ppa:menulibre-dev/devel && apt-get update
sudo apt-get install menulibre

MenuLibre allows you to easily browse through your menu entries, identify duplicates and easily delete them:

Thank you, interesting information, but not really what I asked: I wanted to know a specific "application" entry, not an entire lense. –  berkes Apr 4 '13 at 15:28
    
Ah, sorry. You're right. I read your question wrong. –  Glutanimate Apr 4 '13 at 15:30
    
@berkes I completely overhauled my answer in accordance with your actual question. –  Glutanimate Apr 4 '13 at 15:39
