How to launch Android apps from terminal?

In Linux, I like to launch the applications from the terminal. Most of the time it is the fastest way to launch apps, especially on repeated use. In Android, there are good launchers like **FAST App Search Tool** that will do the job well. But I am still interested in launching apps from the terminal. For that, I installed *JS Terminal*, but I can't see any app names. Even pressing *Ctrl + T* doesn't show any app name.
