Answer the following questions:

1. What is an argument?  Give several examples. 

   Arguments are the portions of the command that are part of the command itself.  the book uses this example:
   $ cp temp tempcopy
   The arguments are  "cp", "temp" and "tempcopy".  these arguments are in numerical order and are part of the execution of that command.  Sometimes a command requires a certain amount of arguments as exampled above, where the copy command requires the file your copying and the name your copying it to; but other commands may not require any.  Options are also considered arguments as well.  

2. Use the man pages to tell me two options for the ls command and what they do.

    -g  just like -l but does not list name
    -h, --human-readable   with -l, print sizes in human readable format (e.g., 1K 234M 2G)

3. Use the internet to look up "The Cathedral and the Bazaar" and tell me what it is and why it is important.

      The Cathedral and the Bazaar is an essay about the differences of two types of software development that was done with Linux.  The bazaar method is where the code that is used for making new releases of Linux available to everyone for viewing and given the ability to scour over the code searching for bugs and error's.  The Cathedral method is where the code is open sourced during the main releases only, but the code used in between releases is only available to the groups using it to develop the releases.
