Line 37: <br /> <pre>cd ~~windows~~Users</pre> This will change you into the <code>~~windows~~Users</code> subdirectory of the <code>C:\</code> directory. <br /> <pre>dir</pre> You should see the names of all the files and directories in <code>C:\~~windows~~Users</code>. <br /> <pre>cd ..</pre> <code>..</code> means "parent directory", so this command moved you up to the parent directory. You were in <code>C:\~~windows~~Users</code>, so now you are in <code>C:\</code>, the root directory. <br /> Line 60: <b>Absolute paths</b> * An absolute path contains the full set of directories from the root of the file system up to your target file or directory. On ~~windows~~Windows, an absolute path ~~with start~~starts with a drive like <tt>C:\</tt>. * You can <tt>cd</tt> to an absolute path from anywhere on the filesystem. * This is an example absolute path: <tt>C:\Users\jesstess\projects</tt> Line 67: * A relative path is calculated relative to your "current working directory" -- the directory you are currently in at a command prompt, as displayed by <tt>pwd</tt>. * This is an example relative path: <tt>projects</tt>. That path only has meaning given a current working directory. If your current working directory were <tt>C:\Users\jesstess</tt>, then <tt>cd projects</tt> would take you to <tt>C:\Users\jesstess\projects</tt> assuming that such a directory existed. If you were in <tt>C:\Users\brad\Desktop</tt>, then <tt>cd projects</tt> would take you to <tt>C:\Users\brad\Desktop\projects</tt>. ~~Here are some examples:~~ ===Tips=== * You can use Tab to auto-complete directory and file names. So from inside the root directory, if you type <code>cd ~~wind~~Use</code> and hit Tab, the command prompt will auto-complete the directory name, and you can then hit enter to change into the <code>C:\~~windows~~Users</code> directory. * The command prompt maintains a command history. You can use the up arrow to cycle through old commands. * Note that the text that makes up the command prompt changes as you move around directories. The command prompt will always give the full directory path to your current directory. Line 85 ⟶ 81: # 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>C:\Users\</tt>, and you want to get to <tt>C:\Users\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 <tt>cd Users</tt> and <tt>cd C:\Users</tt>?
