Shutting Down and Rebooting Gently
Just unplugging power may leave the file system corrupted. To properly shutdown, use the following commands:
sudo halt
or, to reboot:
sudo reboot
Using a Monitor Connected to the Pi
Simply start your Pi with a monitor connected, and it will print out its ip address right before it finishes starting up. You can also get the IP address with the following command:
hostname -I
Also check if your Pi is connected to the internet:
ping yr.no
Should return something like:
PING yr.no (160.68.205.237) 56(84) bytes of data.
From 193.156.90.50 icmp_seq=1 Packet filtered
From 193.156.90.50 icmp_seq=3 Packet filtered
From 193.156.90.50 icmp_seq=5 Packet filtered
(Abort the ping by pressing Ctrl and c.
SSH
SSH is a protocol to securely connect to a computer. Via SSH you can access the command line, just as if you connected to the computer with a monitor and a keyboard. By default, the Pi has SSH enabled.
Windows: SSH via Putty
You can download Putty from here. The Raspberry Pi Foundation has a quick introduction here.
Mac and Linux
On Mac and Linux, SSH is already installed and available within the terminal.
http://www.raspberrypi.org/documentation/remote-access/ssh/unix.md
To log into the Pi via ssh, type:
ssh pi@<ip-address>
Replace <ip-address> with the IP address of the Pi.
Copying a File to the Raspberry Pi
From the Command Line
If you want to copy a file to the Raspberry Pi form your PC, use the following command:
scp <filename> pi@<ip address of the pi>:~/
For example:
scp getmyip.jar pi@192.168.1.106:~/
This will copy the file into the home directory (/home/pi). During the process, you will be asked for the password for the username pi. If you did not change anything, that password is raspberry.
