Context: This is a very basic question

Using Putty and SSH for the first time to do some serious server setup and run into the situation where I have started a process that I do not want to stop.

The process is the gunicorn WSGI HTTP Server (running on Centos 6.3).

The command I used to start the process is (as per their Quick Start):

gunicorn -w 4 myapp:app

At this point in the work session, I have lost the command prompt. This must be such a non-issue that it doesn't even enter into an experienced user's consciousness. But unfortunately at my level of experience, I am left with several fundamental questions:

• Does the fact that I have lost the command prompt mean that the process is still running?
• How do I get back to the command prompt without killing the process?
• How do I come back and monitor the process later?
• How do I eventually kill the process?

Any help is appreciated, thanks so much!
