This should be the system hostname, or the phones name. This name is the one usually registered in the local dns when connected to a wifi network. having the hostname in the PS1 will make it easier for people to set up ssh connections as all they should need is

ssh -p 8022 termux@<phonename>

and/or can add this to their ssh config (assuming the phone is called myphone)

Host myphone
    HostName myphone
    User termux
    Port 8022 
    ForwardX11 yes
    ForwardX11Trusted yes
    IdentitiesOnly yes
    IdentityFile ~/.ssh/termux.key

which allow people to just

ssh myphone

which works with emacs tramp for editing files on the phone filesystem

I don't think Android (as of 5.0 or later) allows setting a system hostname. At least not without root - do you have a root setup where you can test this?

I guess hostname The hostname issue I have looked into, but i cannot find the detail. Usually there is a device ID that is used for the hostname, and this is part of the android platform. If you can publish this, then that would be a good substitute.

The above process also works by using IP address.


And can be added to the documentation

Hello! Android does have hostnames. Hostnames are required of all network devices... normally it is something like "android38793629130". Not being able to use a custom hostname without root is not the same as not having a hostname at all!

Add the following to ~/.bash_profile:

GREEN="\[$(tput setaf 2)\]"
RESET="\[$(tput sgr0)\]"

export PS1="${GREEN}\$(id -n -u)@\$(getprop net.hostname):\$(pwd)${RESET}\$ "

Maybe this can be added to the sshd script, or another termux script that will tell you about your local network environs?
