Line 1: __NOTOC__ [[File:Utilities-terminal.png\|200px]] == Practice navigating from a terminal == 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~~terminal. There are three commands that we'll be using atin athe ~~command prompt~~terminal to navigate the filesystem on your computer: * <code>ls</code> * <code>pwd</code> Line 16 ⟶ 20: Let's practice using these commands. ===Open a ~~command prompt:~~terminal=== You can find the Terminal application at Applications/Accessories/Terminal, or it may already be on your menu bar. Line 71 ⟶ 75: ===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 ho</code> and hit Tab, the ~~command prompt~~terminal will auto-complete the directory name, and you can then hit enter to change into the <code>/home</code> directory. * The ~~command prompt~~terminal 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~~terminal ~~line~~prompt 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~~terminal prompt? # After starting a new ~~command line~~terminal 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~~terminal prompt and a Python prompt? ===Success!=== You've practiced using <code>ls</code>, <code>pwd</code>, and <code>cd</code> to navigate your computer's filesystem from the ~~command prompt~~terminal.
