[Trisquel-users] How to execute a .sh file downloaded on Trisquel

[euleaelias]

Hello, folks! I'm a newbie on using command lines. I tried to execute (run) a  
.sh file of a program I downloaded. It is an Esperanto course. It is called  
Kurso de Esperanto 4. It is available at http://www.ikurso.net . I've tried  
to follow the hints available at web.

I'm using Trisquel 8 beta-version for test.
I checked if the Properties of the file kurso4.sh and it was executable as a  
program.

I then double clicked it and it chose to run it in terminal.

Nothing worked.

Thankfully Yours,
Euleax!
