Change Prompt after executing a command

Is it possible to change the session variable "PROMPT" by a executed custom
command in a bundle?

For example:

karaf@root()> item:add Something
Created item with id 12345 and content "Hello World!"
karaf@root():item:12345>item:change content "42 rules" 
Changed content of item with id 12345 to "42 rules"

Hi Matthias,

You can register whatever you want in the session and check the session
content (like PROMPT_ORIGIN if you want).

Thanks. This works. Is there a possibility to add a session-listener? When i
am in a subshell and set the command "exit", then i need to set the new
prompt, but there is no possibility. I only can "reset" the prompt with
dynamic values, when i am excecution my own commands, but not the "default"
ones.

Or do i have to override the default ones, like "exit".

Hi,

you can change PROMPT property in the command Session.

The command has an access to Session, so you can do:

...
public class MyCommand implements Action {

@Reference
Session session;

public Object execute() {
  session.put(Session.PROMPT, "fooo");
  return null;
}
