This document covers coding on the Pi.
There are three simple ways you can synchronize code between your laptop or the Pi.
Editing on the device is the simplest option if you are familiar with UNIX text-based editors.
- Nano
Beginners may use the pre-supplied nano editor to edit and create files.
Usage:
$ nano filename.py
| Command | Description |
|---|---|
Control + X |
Exit |
Control + O |
write file to the disk |
Control + K |
cut a line |
Control + U |
paste a line |
Control + W |
find in current file |

- Cat
If you need to drop a single text file onto the Pi you can use the cat command and a bash pipe like this:
$ cat > Dockerfile
(Now paste the contents in)
FROM armhf/alpine:latest
CMD ["cat", "/etc/hostname"]
(Now it Control + D)
You'll see your file created in the current directory. I use this technique a lot when working on remote systems.
If you edit the code on your local computer then you can copy files up to the Raspberry Pi like this:
$ scp -r lab2_2 pi@raspberrypi.local:~/
That will copy the lab2_2 folder from your laptop to the home directory on the Pi.
Copying from the Pi to the laptop is also useful:
$ scp -r pi@raspberrypi.local:~/lab2_2 .
You can create a repository on Github and use git push and git pull to synchronize files.
You can mount a NFS or Samba filesystem from the Pi to your laptop or visa-versa. This is an advanced technique and will take some time to setup.
