 I recommend that you copy and paste long commands like this from the eBook into a plain text editor like Notepad, and then make sure that the whole command is properly formatted as a single line, before you then copy and paste it to the command-line. 
 
 Copying and pasting directly from the ebook is likely to include newline characters and missing spaces and so on that break the command.
