The Caps

Those of you moving from Windows to Linux also need to know about "capitalization"

In Linux, capital letters are "not" the same as lower case letter. In other words, Linux is case-sensitive.

Windows is (largely) case insensitive; Windows doesn't care if you type cmd or Cmd, ping or Ping, or if you name your folder Folder or folder, all these are the same.  The exception is with passwords, passwords are case sensitive.

Linux was created differently and intentionally encodes letters in ASCI text .. So, every letter in Linux has a different ASCI encoding.

In ASCI, an upper case letter is a differet character than a lower case letter.

Let me rephrase, with Linux an "R" is not the same as an "r"
In Linux, you can create a directory and call it "Music" and then create another and call it "music" and the system wont complain because these words are not the same.  In Windows you will get an error.

In summary,
Linux letters are encoded differently than Windows, and Linux is case-sensitive.

The "Root" of Everything

Let's talk "root"

The concept of root is essential for any Linux beginner and those moving from Windows to Linux


Root Defined:
Root = The highest level of anything.


Different uses of the concept of root:
Root in the Linux world is used in three different ways:


~ ~ ~



1- The "root user"

"root user" is the user with the highest level of rights on the computer.  In other words, the root user is "the system admin".   This is similar to the Windows admin user, or an administrators group.

People often say "log in as root" this literally mean to log in on your Linux box with the user name "root".

For instance when you log into your email you might type bob@hotmail.com then type your password and log in. Here bob@hotmail.com is your log-in user

Summary:
"root user" = The highest level a user can have on the computer.
"log in as root" = log in with the user name root



~ ~ ~


2- Root of the Operating System (OS)

"root of the OS" is the highest level in the folder structure on the hard drive.  For example "C:/".

In Windows 7 you can get to the root (C:/) by clicking on "Computer" then
root of the OS is the "Default (C:)" under "Hard Disk Drives."


In Windows XP this was called "My Computer"


Summary
"root of the OS" = "C:/"



~ ~ ~


3- The root of the user

"root of the user" is the home folder for that user. This has application settings, photos, docs, etc.
the "root" for any user is the "home" directory or folder for that user

Summary:
"root of the user" = the home folder
