I was playing with Raspberry Pi Model B for quite a long time. Tweaked few settings, wrote couple helper scripts. After some time second Raspberry Pi 2 arrived. I realized that most settings and scripts that were working on previous should do fine on a new one. I needed to copy few files from one Raspberry to another. For this purpose I decided to use Secure Copy (SCP). This is a file sending command over SSH. Raspbian OS already come with SCP installed so you can use it right away. (it it is missing you can install it by running command sudo apt-get install scp).
