The Unix File System

Unlike windows, UNIX has a single global "root" directory / (instead of of a root directory for each disk/volume) All files and directories are case sensitive

hello.txt != hEllO.tXt Directories are separated by / instead of \ in windows

UNIX: /home/nsavva/Documents/cs2043/2015sp/Lecture2/ Windows: D:\Documents\cs2043\2015sp\Lecture2\ "Hidden" files begin with ".": .gimp Lets look at directories in my root directory
