Izvo zvinoreva kuti zviri nyore zvikuru kushandisa ikopi murairo kuti uwane nzira yekushandira:

whereis firefox

Panguva ino zvabuda zvinogona kutarisa seizvi:

/ usr / bin / firefox

/ etc / firefox

/ usr / lib / firefox

Zvose zvaunofanira kuita zvino kuti uwane makamuri ekugovana a Firefox inonyora murairo unotevera:

ldd / usr / bin / firefox

Izvo zvinobva pamurairo zvichava chinhu chakadai:
