Fedora - file association and application launcher.

In Fedora to install an application and et them reflected in th launcher you need to add the entry at
~/.local/share/applications/ - if that need to be shown in the launcher of the logged in user alone
/usr/share/applications/ - if it need to shown for all users

ls ~/.local/share/applications/
AdobeReader.desktop
chrome--Default.desktop
defaults.list
mimeapps.list
SQuirreL SQL Client.desktop

This is how it looks like .

And to associate a fletype to a particular application
Add the entry at
mimeapps.list - located at the same above folders.

The mimeapps.list looks like

[Added Associations]
application/pdf=evince.desktop;
text/vnd.graphviz=gedit.desktop;
image/jpeg=shotwell-viewer.desktop;
text/plain=gedit.desktop;libreoffice-calc.desktop;
application/x-x509-ca-cert=gedit.desktop;
application/xml=gedit.desktop;
text/x-java=gedit.desktop;
application/octet-stream=firefox.desktop;
application/x-trash=gedit.desktop;
application/x-shellscript=gedit.desktop;
image/png=shotwell-viewer.desktop;
application/x-wais-source=gedit.desktop;
application/x-executable=gedit.desktop;
application/x-ica=wfica.desktop


On the left hand side is the mimetype of the file. and
on the right hand side is the entry in the applications folder.

That it.
