How to start executable program from terminal?

I downloaded a program from the internet. I simply took the file from 'Downloads' and put it on my desktop. I can launch the program by double clicking on it. However I cannot figure out how to start this program from the terminal.

I tried the following without luck or any leads:

1. ./ clipgrab-3.4.2.x86_64
2. sh clipgrab-3.4.2.x86_64
3. Typed 'alacarte' into the terminal, in an attempt to find the program of interest to locate name which would allow it to open.
4. Launched program with terminal open to find any hints
5. nautilus-autorun-software clipgrab-3.4.2.x86_64

The settings when I right click the program look like this:

I searched all over 'AskUbuntu' but didn't find the answer. I hope you can shed some light.

Thanks in advance.

Solution 1:

You have a space between ./ and clipgrab-3.4.2.x86_64. It should run if you type ./clipgrab-3.4.2.x86_64 with no spaces.
