Linux ubuntu, adding a launcher shortcut

src: http://difusal.blogspot.com/2015/06/how-to-install-eclipse-mars-45-on-ubuntu.html
0. maybe :
sudo ln -s *eclipse path* /usr/bin/eclipse 
make sure you replace *eclipse path* with the location where you previously saved eclipse - in my case it is ~/Programs/eclipse/eclipse

1. sudo gedit /usr/share/applications/eclipse.desktop 

2. After these commands, gedit - Ubuntu's default text editor - should have opened

3. Copy the following text and paste it there:

[Desktop Entry]
Name=Eclipse
Type=Application
Exec=/home/henrique/Programs/eclipse/eclipse
Terminal=false
Icon=/home/henrique/Programs/eclipse/icon.xpm
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE;
Name[en]=Eclipse
X-Desktop-File-Install-Version=0.22

OR

#!/usr/bin/env xdg-open
[Desktop Entry]
Type=Application
Name=DbVisualizer 9.2.15
Exec=/bin/sh "/opt/DbVisualizer/dbvis"
Icon=/opt/DbVisualizer/.install4j/dbvis.png


4. Save the text file and close gedit
5. A shortcut should have been successfully created 
6. You may have to log off and back in for it to show up

Alternativa, tambien se puede poner aca: .local/share/applications/firefox-dev.desktop
[Desktop Entry]
Name=Firefox Developer                 
GenericName=Firefox Developer Edition             
Exec=/opt/firefox-dev/firefox
Terminal=false
Icon=/opt/firefox-dev/browser/icons/mozicon128.png
Type=Application
Categories=Application;Network;X-Developer;
Comment=Firefox Developer Edition Web Browser.
