سلام
با اینکه بسیار پیگیر منبع آموزشی برای لینوکس فدورا 6 هستم ولی کتابی که تمامی دستورات لینوکس فدورا 6 را داشته باشه پیدانکردم شما دوستان کتابی می تونید معرفی کنید .
چون که باید یک جزوه کامل از دستورات لینوکس برای درس سیستم عامل مدیریت شبکه تهیه کنم .
سایتی هم که به زبان فارسی همه دستورات را داشته باشد پیدا نکردم.
البته کتاب آموزش گام به گام سیستم عامل لینوکس نوشته آقای عباس نژاد ،کتاب خوبی است اما همه دستورات را ندارد . با تشکر
