I am trying to follow the instructions as provided by DuckDNS for pi.

Its all come to grief on the 3rd command:

vi duck.sh

My pi responds with -bash: vi: command not found

Its a Rpi3B running the latest update 6.31.2

It looks like I have tried and failed at this before as the duckdns directory was already created, but I would like to try and get it done this time.

CLI is a totally foreign environment for me. Please be gentle.

sudo apt install vi

or just use nano (easier for a beginner) to edit files.

so I would type "nano duck.sh" instead?

OK, I did that and its given me something useful looking.

Now I have to copy text into that file, but Ctrl-V does not work.

I'm just going to type it in, probably faster.

GRR no idea if that worked.

Installing vi does not work, it says it cannot find the package.

Next command - crontab -e

Opens crontab in nano, ok.

Now I have type this line in at the bottom - */5 * * * * ~/duckdns/duck.sh >/dev/null 2>&1

But as soon as I type the first *, it takes me to File Name to Write instead.

Surely this isnt supposed to be this hard?

Last command tests if the script works

./duck.sh

I guess I went wrong somewhere:

./duck.sh: line 1: unexpected EOF while looking for matching ``'

./duck.sh: line 3: syntax error: unexpected end of file

That looks like you have pasted something into the file and you have a different quotation marks ` ' or "

How are you connected to the pi? Using a keyboard and screen? Using a client on a Windows box e.g. PuTTY?

When you setup the pi, which OS did you install? Lite version? Full version?

@huckster

I couldnt get the paste to work (even ctrl shift v) so I typed it all in.

I found I typed ` where I should have typed ~.

I am connected using Putty on Win10. The pi is running DietPi.

But anyway, I just tried ./duck.sh again and I dont get any errors, instead this

% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 2 0 2 0 0 2 0 --:--:-- --:--:-- --:--:-- 2

Which sort of looks like its working????

The instructions say I can check if its working by typing

cat duck.log

And I should see OK or KO.

Instead it just goes to the prompt.

If you are connected using PuTTY, then copying and pasting into the file on the Pi is quite simple. Copy the line in Windows as you would normally, and when editing the file on the Pi (nano I presume), simply right-click in the PuTTY window.

vi is an editor but to install it, you need to run

sudo apt-get install vim

The package is called vim. However, if you are not a command-line dude then using vi will only confuse things.

I suggest re-editing the duck.sh file and removing all that is there and trying again.

If you copy what you need and edit it first in something like Word on the PC, it can stuff up the quotation marks e.g. `Word is a pain' and that will confuse the Pi.

cat is a command to display the contents of a file (like type in DOS or Windows), in this case duck.log. After displaying the file contents, it returns to the prompt, same as after any command. If it just goes to the prompt, it means that the file exists, but is empty.
