Raspberry Pi’s run on versions on the Linux Operating System. To navigate around command line for your P4WNP1, we need to go over a few different Linux commands.

Commands:

list files and directories:
ls

to access or change directory:
cd <directory name>
example:
cd P4WNP1

to view the contents of a file:
cat <file name>
example:
cat setup.cfg

to edit the contents of a file
nano <file name>
example:
nano setup.cfg

Note: when you edit a file in nano, you will see options at the bottom.
many of these show the "^" followed by a letter, example ^O. The "^" means to use
the Ctrl key. ^O = Ctrl+O

So to save our file we edited, we need to ^O then enter to save. Then ^X to Exit.
