UNIX

4 important Unix commands are cd, ls, pwd, and clear. cd alone will brong you to the home directory but u can also go to specified directory by typing in cd . ls will list components within a directory. like with cd, you can type ls and it lists the components within that directory (ls is equivalent to dir in DOS). the pwd command tells your the location of where you are and its full directory name. clear (cls in DOS) will clear the screen and helps keep you organized. There are other commands just as mkdir (makes directory), cal (shows calendar), exit (exits).

Andy Clark's chapter 6 "Global Warming" is concerning the face that the human brain and technology are evolving into the same thing. Both man and machines depend on each other now.
