The various sorts of backgrounding in Unix
In Unix, there's several ways to put processes into the background,each with its own different set of effects, because Unix processes havevarious sorts of connections to your foreground shell session: their process group , whether or not they areignoring SIGHUP signals, open file descriptors to your tty, and evenwhether or not the process has a controlling tty.

魔間傳奇 – 商業之間？
我會覺得《I Am Legend》 (魔間傳奇) 是有點不想走商業路，但如此製作如此格局，似乎又是非商業不可吧？
影片的最大亮點，當然是在經歷大災難後的荒廢城市：殘破的樓宇、雜草叢生的馬路、斷頭的大穚、空盪盪的街道。在這環
