__NOTOC__
The filesystem on your computer is like a tree made up of folders (also called "directories") and files. The filesystem has a root directory called <tt>/</tt>, and everything on your computer lives in subdirectories of this root directory.
We often navigate the filesystem graphically by clicking on graphical folders. We can do the exact same navigation from the command line.
There are three commands that we'll be using at a command prompt to navigate the filesystem on your computer:
* <code>ls</code>
Line 16 ⟶ 22:
===Practice using <code>ls</code>, <code>pwd</code>, and <code>cd</code>===
(that's an l the letter, not the number 1)
Type each of these commands and hit enter:
Line 63 ⟶ 69:
This lists the contents of the root directory, confirming where you are.
===Tips===
* You can use Tab to auto-complete directory and file names. So from inside the root directory <tt>/</tt>, if you type <code>cd
* The command prompt maintains a command history. You can use the up arrow to cycle through old commands.
===Check your understanding===
Answer these questions. Experiment at the command line if you need to! If you aren't sure about an answer, ask a helper.
# What directory are you in after starting a new command line prompt?
# After starting a new command line prompt, how would you get to the root directory?
# How do you check what files and directories are in your current working directory?
# If you are in directory <tt>/home</tt>, and you want to get to <tt>/home/jesstess/projects</tt>, how would you do that?
# What are 2 ways to avoid typing out a full navigation command? (hint: one requires that you've run the command before)
# What is the difference between a command prompt and a Python prompt?
===Success!===
