How Do You Background A Unix Shell Session In Metasploit

I don't know if i'm asking this question right but i am currently having trouble finding out how to background the session, Background doesn't work, Exit closes it And i'm a bit confused because i can't quite find anything at the moment, In Armitage its open in one window and in the other i can use some of the post exploitation modules on it, I'm trying to do this in the framework, Help would be appreciated thanks :) Hope this helps you... https://www.offensive-security.com/metasploit-unleashed/msfconsole-commands/ https://github.com/rapid7/metasploit-framework/wiki/How-to-use-a-reverse-shell-in-Metasploit For background, ctrl + z or type background when you have shell meterpreter. Thanks it worked :)
