Using the Root User for Linux System Administration – Linux Training Online – Linux Concepts & Terms
There are often several Linux OS (operating system) terms that are similar, the same, or somehow related.
This article will clear up the confusion about the terms: root user, / (root directory) and /root (the home directory of the root user)!
First, you will learn about the root user, and then see a brief description of the / (root) directory and the /root (home directory) of the root user.
Linux Tips: The articles with names ending in “Linux Concepts & Terms” help you learn Linux “geek-speak” (terms). By learning Linux terms (the Linux “lingo”) you will be able to understand Linux concepts and more easily learn how to use Linux. This is an excellent way to start your Linux training.
The root User
To do Linux system administration tasks, like create Linux users and assign permissions to users, you work as the Linux user named root. Read the rest of this entry »

Using Linux Commands to Do Linux System Administration Tasks and Manage a Linux System – Linux Admin
Linux commands are used to do System Administration tasks on many different types and kinds of Linux “server systems”, such as ftp servers, print servers, web servers, dns servers, email servers and dhcp servers.
Linux commands are also used to manage Linux workstations (a.k.a. desktop systems) that are being used for daily office productivity tasks, like word processing and email.
These desktop systems are more common than many “non-Linux” people realize and they are being used to run common Linux programs, like the free Open Office programs (Calc, Impress, Writer, Draw, Base) and thousands of other common, popular and free “office productivity” software programs. These desktop systems are used by millions of people in offices all over the world!
Linux Commands Training Tips: Linux commands are used for System Administration on millions of server and desktop systems to administer and manage these systems. Read the rest of this entry »

Understanding Linux Filesystems & Linux Filesystem Types – Linux System Admin Training – Run Ubuntu
The Default Linux File Systems (Filesystems)
The default filesystems that are recognized by Linux are specified in the text file named filesystems in the /proc directory.
Four of the filesystems that are commonly found on a Linux system are: ext2 (old and less common), ext3 (very common), iso9660 and swap.
Some Linux distributions also use other filesystems.
For example, instead of the ext3 filesystem, the SUSE and openSUSE distributions use the reiserfs filesystem by default.
In addition to the above filesystems, by default Linux can also recognize a partition that is a “swap” partition.
Depending on the documentation that you are reading and the command or utility that you are using, “swap” is not typically considered to be a filesystem type. It is a type of partition that is treated by the OS as virtual memory (where hard disk storage space works as though it is RAM memory).
The following is a description of some of the commonly used Linux filesystems. Read the rest of this entry »
