Thanks for the replies. I know that using at we can configure bit torrent to start or stop. But main problem is about Wake up from Hibernate.
In Xp, I used to do that using Auto Power on and shutdown program and even xp built in scheduler has same facility.
I got one simple program to launch program at given time
But do you know any command to wake up from sleep
Even i found command for hibernating in etc/gdm/gdm.conf
sudo pmi action hibernate
So if you are expert please find any command to wake up
