LINUX USE AND WORK WITH "VI EDITOR"

The editor found nearly every UNIX and LINUX system is “VI editor”, originally written by Bill Joy. It is simple to use but incredible capable editor features of the some cryptic commands set. Older more experienced UNIX and LINUX user continue to use “VI” intensively during computing session.

The “VI” commands work by using insect or editing mode and a viewing (or command mode).

To start editing, tap the ! key to insert text. Or to append text, when finish use ESC key to toggle out of the insert or append modes and into the viewing (or command mode) to enter a command type a semicolon (;) write the file name and press . The “VI” supports many complex editing operations and numerous commands, to accomplish work by using a few basic commands.

DESCRIPTION	COMMANDS
CURSOR MOVEMENT	h, j, k, l (left, down, up & right).
DELETE CHARACTER	x.
DELETE LINE	dd.
MODE TOGGLE	ESC, insert (or i).
QUIT	q.
QUIT WITHOUT SAVING	q!
RUN AS SHELL COMMAND	Sh (use “exit” to return).
SAVE FILE	w.
TEXT SEARCH	/.

TAKE IT EASY LINUX INSTALLATION

Ø To get start, first insert the RED HAT LINUX CD in CD-ROM and reboot the computer, first scene boot screen that offer the variety of option for booting.

Ø start the installation using graphical interface. The graphical interface supported a mouse and offer check boxes and text field for choosing software, configuring options.

Ø After check CD-ROM or skipping the checking, presented with a welcome screen, press to continue and then select the language for the installation.

Ø Then it will ask to select a keyboard. Choose the appropriate keyboard option which can be used to configure Linux support a specific language.

Ø Select the mouse type for Linux session, and also Linux support USB devices, including USB mice.

Ø To select the new partition on the hard drive, use add partition dialog box assign a mount point (such as /root/) assign a file system (like ext2, ext3, RAID, SWAP etc) assign the size of the partition and then press OK.

Ø Then screen appears asking to select a boot loader for booting RED HAT LINUX, GRUB and LILO are two types of boot loader it installed in the first sector of the Linux partition.

Ø And then to enter password, it will subsequently need to enter three passwords (BIOS, boot loader and login) in order to access Linux, then highlight OK and press .

Ø If installed the network adopter so select the graphical network Administration tools. Then insert the networking configuration information, when finish click OK and select firewall configuration.

Ø The medium setting might be acceptable for use and Internet protected by the firewall and served by an Internet gateway.

Ø And then select to install the software. If choose the personal desktop, workstation, or other installation type, the software packages appropriate for that installation will be selected. Each package provides many different individual software packages.

Ø After finishing the installation press OK and RED HAT LINUX will eject any inserted CD in CD-ROM. Reboot system the GRUB boot loader will present a graphical boot prompt and LILO boot loader also provide a graphical display…

LINUX CHECKING HARDWARE COMPATIBILITY

RED HAT LINUX software for Intel-based PCs is compiled for the minimum x 86 platforms supported by the Linux Kernel, x 386 CPUs family.

If a particular Laptop or PC model, it should also check with it manufacturer for Linux support issue. Enlightened manufacturer now offer Linux preinstalled or have in-house Linux hardware certification programs.

LINUX PREPARING FOR HARD DRIVE STORAGE

Making room of RED HAT LINUX how to use existing hard drive space it use only one operating system on computer. A full install of Linux will require at least 5GB hard drive space just for the software, so if plan to install everything, 10GB hard drive will be ideal for a workstation.

NOT HIGH HARDWARE REQUIREMENT FOR LINUX INSTALLATION

RED HAT LINUX can be installed on and will run on a wide verity of Intel-based hardware. This inclusion legacy platform up to the latest workstation, rack-mounted system and multiprocessor server available from the entire tier of computer hardware vendors, small, medium size and even large scale of RED HAT LINUX are available such as IBM.

INITIAL PREPARATION FOR INSTALLATION OF LINUX

There are many factors of using RED HAT LINUX as a computing solution. The current distribution can fill many roles of various tiers and hardware platforms because RED HAT LINUX offered pre-configured installation script of fit development workstation, e-commerce, server and mobile platform needs only the required software will be installed.

CHARACTERISTICS OF LINUX OPERATING SYSTEM

• Linux is the first full operating system available for Intel’s new titanium CPU and supports are available for HP, Compaq’s Alpha and Sun Microsystems SPARC CPUs.
• Linux provide for a much wider user based extend the life of older working hardware and help save money for home, small business and even corporate user.
• Linux can be work as a server platform; Linux is fast, secure, stable, scaleable and robust. Linux Kernel easily support multiprocessor computer system (optimized for eight CPUs) large amount of system memory (up to 64GB RAM) individual file size in excess of hundreds of gigabytes.
• Red Hat Linux also spent quite a bit of effort on developing a comprehensive suit of graphical administrative programs or software tools.
• The major features of Red Hat Linux are the inclusion of the latest GNU gee compiler system, supporting C/C++ language program development. The newest major version of the Apache Web Server and the Common UNIX Printing System (CUPS) which support more than 1000 different printers.

INTRODUCTION TO LINUX OPERATING SYSTEM

Linux is an operating system which is the product of RED HAT in 1994 MARC EVING and BOB YOUNG combine to create “RED HAT LINUX” in order to develop release and easy to installed, easy managed and easy to used and combining the Linux Kernel with (GNU), software tools, drivers, utilities, interfaces and other software like the xfree86 project window system.
