Question: Very new to Linux, but I thought I understood file exploration from the command line.

**The problem:**
I can't figure out how to navigate my files or directories, the console isn't displaying any feedback when I type "ls" or "pwd" or "cd". Example:

```
tyler@ip-172-31-13-165:~$ cd /home/tyler
tyler@ip-172-31-13-165:~$ ls
tyler@ip-172-31-13-165:~$ ls /home/tyler

```

It's not showing me anything! How do I know what directories exist?

**what I've done so far:**
I have recently created a Ubuntu 14.04.1 micro instance with AWS, which I'll be using to practice webapp deployment. I am connecting to the instance via puTTy on Windows 7. I created a new user: tyler with sudo privileges, as follows:

**What I want:**
I want some way to explore the files/directories I've created/that have been created for me using the command line (I don't want to rely on a GUI).

Answer: 
Perhaps there's nothing in that directory?

Try "ls /" which should list contents of root directory.
As alternative, `tree` command gives you more complex information regarding directories in tree view.

Install it with `sudo apt-get install tree`
and try to type `tree /`
