How to launch console application from terminal in Linux?

Question

I am using ubuntu distro,for your information. I have a console application (doesn't get any parameter, I just need to launch it.) How can I launch it from terminal?

And second question is that since console applications in Linux does not have a "window" can I see console ouputs on terminal?

I know this is a very basic question, but believe me I couldn't find an answer.

Answer 1

In terminal:

cd to the application directory

then type

./appname

You can see the output.
