Sample SSH output - mikec964/chelmbigstock GitHub Wiki

You can use ps to see if you are in an SSH shell.

First, here are the processes running before SSH login:

Robin:hadoop-1.2.1 hadoop$ ps
  PID TTY           TIME CMD
  774 ttys000    0:00.03 -bash

Now we login and check the processes again:

Robin:hadoop-1.2.1 hadoop$ ssh localhost
Last login: Sat Jan 24 10:47:11 2015 from localhost
Robin:~ hadoop$ ps
  PID TTY           TIME CMD
  774 ttys000    0:00.02 -bash
  917 ttys000    0:00.02 ssh localhost
  922 ttys001    0:00.01 -bash
Robin:~ hadoop$ logout
Connection to localhost closed.

Pressing control-d or typing logout will logout of an SSH session.
