Should work:

sudo eopkg install ruby imagemagick xclip
sudo wget https://raw.githubusercontent.com/gyazo/Gyazo-for-Linux/master/src/gyazo.rb -O /usr/bin/gyazo
sudo wget https://raw.githubusercontent.com/gyazo/Gyazo-for-Linux/master/src/gyazo.desktop -O /usr/share/applications/gyazo.desktop

    wiedymi It should be in your menu, you may need to run sudo update-desktop-database to refresh the database.

      Justin It need's to be executable. Also the icon has to be included.

      EDIT: I tried this application. It uploads the screenshot directly into web "https://gyazo.com".

          algent Ah maybe because I cloned it from git it was already executable. Yeah, that's how I understood the program worked. If it's supposed to act differently I'm not sure what needs to change.

            @wiedymi Other steps that I did to make it work.

            sudo chmod +x /usr/bin/gyazo

            Downloaded the icon in ~/stuff (didn't find a better name)
            https://raw.githubusercontent.com/gyazo/Gyazo-for-Linux/master/icons/gyazo.png

            And then edited desktop entry to include the icon.
            sudo gedit /usr/share/applications/gyazo.desktop

            The line "Icon" from this:
            Icon=gyazo
            to this:
            Icon=/home/algent/stuff/gyazo.png

              algent Let me ask you a stupid question: how come no path to the executable file? This is a desktop launch icon we are making. I know I'm missing something here.
              edit:typo

                  brent Me either don't understand well the "Path" line. I have read something here and here and made some tests but I have failed.
                  The most important thing is to specify the full path of executable file in "Exec" line. In this case the executable file "gyazo" is in system bin folder "/usr/bin/" and it was not necesary, if it were somewhere else then it should be specified, like this one:

                  Icon=/home/algent/.appimage/FreeCAD/FreeCAD-logo.svg
Exec=/home/algent/.appimage/FreeCAD/FreeCAD.AppImage

                      algent Interesting. So when making a simple desktop file, the solus operating system (or whatever) makes Exec=/usr/bin as a default. I learned something valuable about scripting, thank you. Hope I got that right.
