Homecooked bash script questions

[sudo_rm_ignorance]

I have a homemade script which is basically an automated way to manipulate packages. The code itself runs just the way I want it to. My question is about starting it: I double-click on the desktop icon for it, am prompted about displaying / running / running in terminal / do nothing, then have to click "Run in terminal", after which it works great. I would like to just have it run without going through the prompt every time. I tried just typing the file name into a terminal as if it were a package, I get:

txtPackMan: command not found

Makes sense to me that THAT approach doesn't work, but I can't think of anything else. Is there an easy way to do this?

**EDIT: Never mind...found another thread that basically asked the same thing.
