* Everything is a file
  1. Name some 'files' in a standard unix filesystem that aren't very file-like.
  
    - Processes - startup process (init.d), deamon processes
    - scripts/commands - SSH/Ifconfig - files that are available in the PATH, that execute code
    
  2. Identify some places where we use file descriptors for non-file content as part of the development process (hint: sockets are a good example here).
  
    - Sockets - FIFO stream of bytes between endpoints. not file content, but can be seen as a file
    - Pipes - Again FIFO stream - Does not exist as a file, no process can open it. Instead processes share them and the calling           method inherits the file descriptors
