Module 3

1. What is an argument?  Give several examples.

    - and argument is basically a supplement to a command. It can be a few different things, such as a filename or number, that follows the command to give it some instruction. 

   - some of examples of an argument are '-l' which follows 'ls' in order to list it in a long and more informative format. another example would be '/etc' which can follow the 'cd' command to tell the system to change to the /etc directory. a command line can have several arguments, such as 'ls -a -l' (in which '-a' and '-l' are arguments) that will both list hidden files as well as list in the long listing format. 

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

    - as i listed above, two options for the ls command can be -a (which will list hidden files) and -l (which will give the long listing of details). 

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 a book by Eric S. Raymond, who is a computer programmer and developer of open source software. The reason it is important is because it details how open source software can be developed to a maximum effort. The book lists 19 guidelines as to how development stability can be reached. Raymond said that open source software should follow the Bazaar style (where source code can be read by anyone) vs the Cathedral style (where source code is only available after a software release), which helped open up development and create a more bug-free environment for open source software.
