Ok on typing in:  
$ mkdir .mosquitto replies - cannot create directory .mosquitto: read only file system

I tried:  
$ ls replies - cannot open directory : permission denied

It doesn't seem to like any Linux style commands

Are you doing this on the phone? Looking back at my notes I use ssh to connect to it and was able to do everything from my laptop.

Try  
`cd /data/data/com.termux/files/home`  
to see if that gets you do the right place.

Seems like a strange editor when used on the phone! Edit: hold on just noticed the file already exists sorry. Can I create a folder and create a file using this editor? I'm not sure

What is in the folder?  
`ls .mosquitto/`  
If the conf file is already there then you should just be able to add the new bit on the end. I installed the editor nano.  
`pkg install nano`  
but again I did everything through ssh rather than on the phone.

ls .mosquitto doesn't return with anything, no list just a $ prompt.

Will try to ssh to the phone as working on a small touch screen is a real pain.

So the folder exists but is empty, so you should just be able to create the conf file.

Folks.  
I went down the Raspberry pi zero 2 W route in the end and enabled it's hot spot to set up a small local network. I was going around in circles trying to use Termux on the Android phone. I may come back to it at some later date though. Thanks for everyone's help especially Colin as you've helped me out a few times in the past and I'm very grateful.

Cheers.
