I have not used NS2, but I will try my best to help. If the executable is stored in a folder that is displayed in the output of "echo $PATH" then the app should be capable of launching by just typing the name. Please make sure that the app is executable and that your path is located in your path environmental variable.

Does the app run when you attempt to execute it directly from the containing folder?
