Hogyan tudok linux alatt programot meghívni shell nyelven?

Sziasztok!

Van egy program. Mjpg_streamer és egy külön mappában van. Hogyan tudom shell ben meghívni a mappa tartalmát és indítsa el az általam megadott szempontok alapján.

Van egy konfigurációs fájlom is hozzá, mely maga a funkciók és külön a konfigurációkat tartalmazza.

Ezzel szeretném használni.
