How to change the default prompt in fedora toolbox?

Project Discussion
#1

Hi!

I use a couple of containers every days and sometimes I forgot in which container I’m logged on. What is a easy why to set a default prompt that when I enter in a container with toolbox shows me the name of container?
For example, I have a container created with name dev-go, so it will be great if I could a prompt format like this:
⬢[masch@toolbox-dev-go ~]$

Thanks!

Last that I checked, I don’t think toolbox exposes the container name inside the container in any way. There was some discussion about doing that though: https://github.com/containers/toolbox/issues/98

If you want to do something a little hacky, you can store a file in each container that gets read into your prompt.

Thanks for the tip!
I followed the issue that you suggest me and I’ve applied the next modification on my local toolbox script and It works!!

Also I applied the same fix on the new toolbox migration written on Golang and it doesn’t work.
When I enter on I get I get the following error:

I don’t know how does it work on the toolbox script version and it doesn’t on the Golang version.
