======Project: FILESYSTEM SAFARI======

A project for Unix/Linux by Derek Girardi during the Fall 2011.

This project was begun on 09/20/11 and is anticipated to take 1 week. (Upon completion you can correct this with the actual length).

=====Objectives=====
The purpose of this project is to search through the directories and files of unix. We are to discover how each directory is organized, what is contained in each and what we could use each directory for. We hope to be able to navigate through the directories with ease knowing where files are located and how they are organized. Start truly knowing the filesystem of unix.

=====Prerequisites=====
In order to successfully accomplish/perform this project, the listed resources/experiences need to be consulted/achieved:

  * cd command
  * ls
  * -l argument to ls
  * understanding of paths, absolute and relative

=====Background=====
 The purpose of this is to discover directories. To see what they contain and see if i will need to use them or not. Just a general knowledge of the filesystem on unix. The filesystem is a single directory hierarchy. Its starts from root and continues on into directories and sub directories. We use this to organize all our files neatly and in a easy to find manner. To separate all of these directories you will see a forwardslash or '/'. This is what we use to separate and navigate through these files and directories. The cd command will help you navigate to the home directory or any other directory you choose. Either 'cd' or 'cd "directoryname"' will navigate you around. Once inside those directories you will use the ls command, which lists files within. then you can use the '-l' arguement with the ls to give more detail of each file or sub-directory. And each path has a different kind of path. It could be either relative or absolute. With an absolute path, you know exactly where you are going, the path is a deffinite. A relative path is a path towards what you are trying to find, but it might go exactly where you want. It kind of wanders in a way. This is filesystem in linux and some simple commands that will help you understand and navigate these directories.

=====Scope=====
To get a better understanding of the layout and structure of the UNIX filesystem, an exploration is in order. Using your observation skills and references, explore the various major directories on the system (starting with '/') and describing the intended purpose of each directory:

  - what types of files does it contain (regular, directory, special)
  - what is the organizational value of that directory (config files, basic tools, admin tools, etc.)

Some of the directories you will want to explore are:

  * /
  * /bin
  * /dev
  * /etc
  * /home
  * /lib (/lib32 vs. /lib64)
  * /mnt
  * /proc
  * /root
  * /sbin
  * /tmp
  * /usr
  * /var
  * /var/log
  * /usr/bin
  * /usr/sbin
  * /usr/src
  * /usr/local
  * /usr/local/bin
  * /usr/lib

=====Attributes=====
State and justify the attributes you'd like to receive upon successful approval and completion of this project.

  * files and directories: files and directories are the focus of analysis in this exercise

=====Procedure=====
The directory '/' :
<cli>
lab46:~$ cd /
lab46:/$ ls
bin   dev  home        lib    lib64       media  opt   root  selinux  sys  usr  vmlinuz
boot  etc  initrd.img  lib32  lost+found  mnt    proc  sbin  srv      tmp  var
lab46:/$ 
</cli>
1. In the '/' directory it mainly contains more directories and some data files

2. This contains your main directories in which you will most commonly visit. These are like the big directories of the system. Everything starts here.

The directory '/bin' :
<cli>
lab46:/$ cd /bin
lab46:/bin$ ls

1. The files in here are mainly consisted of executable files, with a few data link and special files.

2. The organizational value of this is where it holds files for commands of the system. system critcal programs.

2. These files are special files for all the devices on the system

1. Mainly more directories and regular files with a few executable files.

2. This is mainly configuration fies for the system and various programs in it.

lib32 and lib64 are the same, one is just 32 bits and the other is 64 bits.

1. This is mainly regular, data and a few directories.

2. This is a folder system for critical libraries.

The directory '/mnt' :
<cli>
lab46:/mnt$ ls

1. Nothing is in here

2. This can hold media files, we just dont have any in there right now.

1. Lots of data and special files.

2. Contains every system library that programs require to run


=====Reflection=====
 There are alot of directories and files contained in the linux filesystem. There were more than i actually knew about and i believe i have only scratched the surface of files. I bet there are more hidden among all of these, just got to poke around and find them. Alot were easily accessible, and some i could not enter. Some files i was able to use, some wouldn't let me touch them at all. basically you just got to find which ones you can see and use, and use them effectively.
 But there are so many more files, that i believe makes this a powerful system to use.
