Basic Linux Commands for The Young

noreply@blogger.com (wawasan dunia) — Wed, 18 Jan 2012 01:15:00 -0800

Basic linux commands for The Young - Just as when you type a command at the DOS command line or command line in Linux is also typed at the prompt and end enter to execute the command. The command line is a more efficient way to do any work therefore Linux users still rely on this method to work. We recommend that the young should know and at least once used this command line because someday the knowledge of these commands can be very necessary.the basic commands linux system maybe some of you already know, if of you who do not know well in the following basic commands linux is very complete and I collated.

Linux Commands :

cat : Sends file contents to standard output. This is a way to list the contents of short files to the screen. It works well with piping. Sends the contents of the ".bashrc" file to the screen. ex: cat .bashrc
cd : Change directory
- cd /home = Change the current working directory to /home. The '/' indicates relative to root, and no matter what directory you are in when you execute this command, the directory will be changed to "/home".
- cd httpd = Change the current working directory to httpd, relative to the current location which is "/home". The full path of the new working directory is "/home/httpd".
- cd .. = Move to the parent directory of the current directory. This command will make the current working directory "/home.
- cd ~ Move to the user's home directory which is "/home/username". The '~' indicates the users home directory.
cp : Copy files
- cp myfile yourfile = Copy the files "myfile" to the file "yourfile" in the current working directory. This command will create the file "yourfile" if it doesn't exist. It will normally overwrite it without warning if it exists.
- cp -i myfile yourfile = With the "-i" option, if the file "yourfile" exists, you will be prompted before it is overwritten.
- cp -i /data/myfile = Copy the file "/data/myfile" to the current working directory and name it "myfile". Prompt before overwriting the file.
- cp -dpr srcdir destdir = Copy all files from the directory "srcdir" to the directory "destdir" preserving links (-p option), file attributes (-p option), and copy recursively (-r option). With these options, a directory and all it contents can be copied to another directory.
dd : Disk Duplicate
- dd if=/dev/hdb1 of=/backup/ = The man page says this command is to "Convert and copy a file", but although used by more advanced users, it can be a very handy command. The "if" means input file, "of" means output file.
df : Show the amount of disk space used on each mounted filesystem.
less
- less textfile = Similar to the more command, but the user can page up and down through the file. The example displays the contents of textfile.
ln : Creates a symbolic link to a file.
- ln -s test symlink = Creates a symbolic link named symlink that points to the file test Typing "ls -i test symlink" will show the two files are different with different inodes. Typing "ls -l test symlink" will show that symlink points to the file test.
locate : A fast database driven file locator.
- slocate -u = This command builds the slocate database. It will take several minutes to complete this command. This command must be used before searching for files, however cron runs this command periodically on most systems.
- locate whereis = Lists all files whose names contain the string "whereis".
logout : Logs the current user off the system.
ls : List files
- ls = List files in the current working directory except those starting with . and only show the file name.
- ls -al List all files in the current working directory in long listing format showing permissions, ownership, size, and time and date stamp
more : Allows file contents or piped output to be sent to the screen one page at a time.
- more /etc/profile = Lists the contents of the "/etc/profile" file to the screen one page at a time.
- ls -al |more = Performs a directory listing of all files and pipes the output of the listing through more. If the directory listing is longer than a page, it will be listed one page at a time.
mv : Move or rename files
- mv -i myfile yourfile = Move the file from "myfile" to "yourfile". This effectively changes the name of "myfile" to "yourfile".
- mv -i /data/myfile = Move the file from "myfile" from the directory "/data" to the current working directory.
pwd : Show the name of the current working directory
- more /etc/profile = Lists the contents of the "/etc/profile" file to the screen one page at a time.
shutdown : Shuts the system down.
- shutdown -h now = Shuts the system down to halt immediately.
- shutdown -r now = Shuts the system down immediately and the system reboots.
whereis : Show where the binary, source and manual page files are for a command
- whereis ls = Locates binaries and manual pages for the ls command.

OK basic linux commands for The Young I give can hopefully increase your knowledge about linux .. and attempt try it by you,, good luck

Logging in and Logout on Linux

noreply@blogger.com (wawasan dunia) — Wed, 18 Jan 2012 01:13:00 -0800

So, this time if you have installed linux on your computer, it is very easy to logging in and logout in how your computer. The following means logging in and logout on linux:

logging in
When you complete installing Linux and booting the system you should see a login prompt on your monitor. When you did your Linux install you should have set a root password. You may have also created a user with a password. Therefore to log in, you will want to type the name of a user or "root" for the login name and enter the appropriate password. If you logged in as a normal user and know the root password and want to use administration commands, you may use the command "su" to become a "super user". Some systems also support the "sudo" command, which allows administrative privileges on a command by command basis.

Logging out
Use the command "logout" to exit a given session. If you have logged in, then typed "su" to become a superuser or another user, you may need to type "exit" until your SHLVL environment value is 1. Then you can type "logout" to exit your session. The "exit" command will take you back to previous shell levels.

well, that's the way for logging in and logout on linux in your computer. how? easy is not the way, if there is still not understanding please ask away .. ok good luck ..

Getting Started with Linux For the young

noreply@blogger.com (wawasan dunia) — Wed, 18 Jan 2012 01:12:00 -0800

Getting Started with Linux For the young - to begin try own Linux installation and asked a friend who was steeped Linux. After that you can also follow courses to deepen Linux Linux material. And then is to find the experiences of troubleshooting on Linux. All of the above certainly requires determination and courage, as most beginners who want to learn Linux collided with a few things. For example with the installation, there are still many who are reluctant and even afraid to start installing Linux on his computer. But you can use software such as VirtualBox is free to start, even with your computer's RAM minimum requirement I would suggest is 1 GB.

The main thing to remember is that Linux is different. There is lots to learn, so you need some patience and perseverance. This part assumes you have an install CD with some version of Linux on it. Most can be installed directly from the CD if you want. You can do this by setting your BIOS with an option to boot from the CD. If you can't do this, you will need to get or make a boot floppy. Usually there are utility programs on the CD, usually "rawrite" that can be used to make a boot disk from a DOS environment. Some systems also require a root disk to be made.

To make a boot floppy from the Redhat CD, issue the below commands. The example assumes your CD is on drive D and you are running DOS.

D:
cd /images
/dosutils/rawrite

Enter "boot.img" for the source file and "a:" for the destination.

Important Note!!
I have noticed many times that when people install Linux they will not have the capabilities they want or may get error messages when their system starts. Many distributions allow the following choices or more for their installations:

Workstation - For no or minimal networking. Only client services is installed, so if you use this installation, don't expect to telnet to your system since the service was not installed. Use this installation if you don't have a network card or will not want to provide any network services.
Server - Installs most packages.
Custom - Allows you to select the packages you want to install.

Experience is the best teacher. I often run into few cases after Getting Started with Linux For the young , the more often you find a problem or perform troubleshooting in Linux then you will be more proficient in Linux. Sometimes some cases it is not too complicated for some people but this case has become a complex issue and as if there is no solution. so good luck, enjoy it.

The Linux Operating System Section

noreply@blogger.com (wawasan dunia) — Wed, 18 Jan 2012 01:10:00 -0800

The Linux Operating System Section - This section contains a large amount of tutorials and information about Linux. I present a form that allows you to read it and do not need hard to find. some of you may already have heard of linux, some stories Linux users, who generally do their own install and configuration of the system, are more likely to understand the technology than users of Microsoft Windows or Mac OS. They are often called hacker or geek. But the stereotype is increasingly reduced with increasing user-friendly nature and the growing breadth of Linux distribution users. Linux has made a pretty good achievement in the server computer market and special-purpose computer, such as image rendering engine and a web server. Linux is also gaining in popularity in the desktop computer market.well to more clear about the linux operating system I will explain.

Linux is a principle to a combination of LAMP-server program, short for Linux, Apache, MySQL, Perl / PHP / Python. LAMP has achieved widespread popularity among developers Web.Linux also often used as the operating system embeded. Linux procurement costs low allows its use in equipment such as the Simputer, a low-cost computer that is aimed at low-income population in developing countries. With desktop environments like KDE and GNOME, Linux offers a user interface more like the Apple Macintosh or Microsoft Windows instead of a text line interfaces such as Unix. Therefore, more graphics program can be found on Linux that offers a variety of functions that exist in commercial utility.

Linux Operating System consists of the kernel, system programs and application programs. The kernel is the core of the operating system that governs the use of memory, input output devices, processes, use of the files on the file system and others. The kernel also provides a set of services used to access the kernel is called a system call. This system call is used to implement the various services needed by the operating system. Program system and all other programs that run on top of the kernel is called user mode. The fundamental difference between the system program and application programs are programs that the system needed an operating system can run while the application programs are programs that are required to run a particular application. Example: The daemon is a program of systems and word processing (word processor) is an application program.

Important part of the Linux kernel consists of several important parts, such as process management, memory management, hardware device drivers, filesystem drivers, network management and others. But the most important part is the management process and memory management. Memory management to handle the memory usage, swap area, parts of the kernel and for the buffer cache. Management process to handle manufacturing processes and process scheduling. At the base of the kernel contains a hardware device drivers for each type of supported hardware.

Introduction To Linux for The Young

Tutorials Computer Technology comes to you but I can not guarantee accurate information for you, I provide suitable reference only and I know that I get. hopefully a bit of information I can give satisfying about this Linux guide. you can disseminate this article and requested permission to modify the before Anyway with me . The main goal of this tuorials is to help the reader more quickly discover what those tools and commands are and thereby learn faster. This is done by categorizing capabilities into various sections which describe various operating system functions.
Here are described some of the advantages of Linux compared with other operating systems. And here are some facts of the things that benefit by using the programs and filesLinux:

Basically all the data stored on the hard disk even though there are many situations where data is stored on floppy disks.
Linux provides some special process in which the terminals, printers and other hardware devices can be accessed as we access files stored on hard disk or diskette. When the program runs, the program is run from the hard disk into RAM, and after the run will be named as a process.
Linux provides services for creating, modifying programs, processes and files.
Linux supports the file structure is hierarchical.
Linux operating system is one that belongs to the class of the operating system that can do multitasking. Multitasking itself is a state where an operating system can do a lot of work at the same time.

In addition to multitasking, Linux can also support multiuser. Namely operating systems at the same time can be used by more than one user who entered into the system. Even for Linux also supports to multiconsole which at the same time at the computer instantly without having to go through the network and allows more than one user entered into the system.
This Tutorials attempts to give examples and reasonably full explanations about the various tools involved, but more emphasis has been placed on having a reasonable listing of tools. Therefore some information may be repeated in various sections or documents in order to avoid the necessity of looking in many areas for complete information.

Parts of Computer Technology Basics

noreply@blogger.com (wawasan dunia) — Sat, 7 Jan 2012 15:39:00 -0800

Part of Computer Technology Basics it seems you should know if a part of the computer is damaged you be know where the location of the damage. Computers Technology now in circulation are increasingly sophisticated and much in demand by many people, maybe including yourself. you should know in it has an important component.The following Parts of Computer Technology Basic:
1. Hardware
hardware are all part of the physical computer, and are distinguished by the data in it or who operate in it, and are distinguished by the software (software) that provides instructions for the hardware to complete the task. The boundary between hardware and software will be a little blurry when we speak about firmware, because this firmware is software that is "made" into the hardware. This firmware is the area of computer science and computer engineering, which is rarely known by the general user.Just an example below:

2. Software
The software is a general term for data that is formatted and stored digitally, including computer programs, documentation, and a variety of information that can be read and written by a computer. In other words, the computer system that is not tangible. This term highlights the differences with the computer hardware.
Computer hardware are all part of the physical computer, and are distinguished by the data in it or who operate in it, and are distinguished by the software (software) that provides instructions for the hardware to complete the task.
The boundary between hardware and software will be a little blurry when we speak about firmware, because this firmware is software that is "made" into the hardware. This firmware is the area of computer science and computer engineering, which is rarely known by the general user.

3. PROCESSOR
This time we will discuss the processor. What processor does it? How does it look like? Functions for what?
Below you will try to explain what that processor. Processor is a very important part of the computer. He can be likened to a computer brain. Ie an electronic circuit that functions to logically respond to and process all the instructions that turn on the computer.
Take a look at the picture below:

4. KEYBOARD, MOUSE AND MONITOR
Well, this input section consisting of keyboard and mouse. In the 1990s, just a keyboard input device only. Further development began to emerge mouse, pen (pen-shaped). There is now a form of finger touch input device (touch screen) and sound. Commonly used for home computers is the keyboard and mouse. Its function is of course for entering data. Finally, the monitor, output while, because it just seemed to make while alone on the screen. Its function is to see the results of inputs or programs that are currently active.

ok that's overview of Part of Computer Technology Basic maybe went on time maybe someday computers technology will be increasingly more sophisticated and cool, and technology have become a necessary requirement to have.so to know the basic parts computer can increase your knowledge ...

Understanding Application Computer Technology

noreply@blogger.com (wawasan dunia) — Sat, 7 Jan 2012 15:38:00 -0800

Understanding Application Computer Technology It is very important that you can learn a lot about application or app. in my post about Understanding of Operating System Computer Technology I hope you have understanding who is only little.. May be you have ever heard about using an application or app. An application (or app) is a type of software that allows you to perform specific tasks. Applications for desktop or laptop computers are sometimes called desktop applications, and those for mobile devices called mobile apps.

Application programs are meant to accomplish specialized tasks they are designed for :

-. Word Processing : A word processor allows you to write a letter, design a flyer, and create many other kinds of documents. The most commonly known word processor is Microsoft Word .for example try look below:

- Email or electronic mail : becoming more and more popular as people learn to communicate again with written words. For many purposes it is superior to a phone call because you don't have to catch the person in and you can get straight to the point. No time is wasted on casual conversation. It also leaves a written record to refer back to for a response or if you forget who said what. Try look this picture below:

- Communications : These programs temporarily connect computers to each other to exchange information. They may use telephone lines or dedicated cables for the connection. for example, to work at home on the weekend and transfer all you've done to your computer at work before you leave home.Try look this picture below:

Web Browsers : A web browser is the tool that you use to access the World Wide Web. Most computers come with a web browser pre-installed, but you can also download a different one if you want. Examples of browsers consist of Internet Explorer, Firefox, Google Chrome, and Safari. let's see some examples below:

Games : There are many different games that you can play on your computer. Many action games require a lot of computing power, so they may not work unless you have a newer computer. let's see some examples below :

I hope you had a fruitful experience reading Understanding Application Computer Technology and can be for practiced by you.maybe someday you'll find something new and can be useful for the crowds ..

Understanding of Operating System Computer Technology

noreply@blogger.com (wawasan dunia) — Sat, 7 Jan 2012 15:38:00 -0800

Understanding of Operating System Computer Technology this time will discuss about Operating System or OS.I hope you also know about Computer Basic. you have been hear about Operating system or OS. The Operating System is a program that conducts the communication between the various pieces of hardware like the video card, sound card, printer, the motherboard and the applications. An Operating System is the most important software that runs on a computer. It manages the computer's memory, processes, and all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's "language." Without an operating system, a computer is useless.
Some operating systems Computer Technology are very large and complex, as well as the input depending on user input, while the other Operating Systems are very small and made with the assumption that work without human intervention at all. The first type is often referred to as a Desktop OS, while the second type is the Real-Time OS, for example is :

1. Windows
Microsoft created the Windows operating system in the mid-1980s. Over the years, there have been many different versions of Windows, but the most popular ones are Windows 7 (released in 2009), Windows Vista (2007), and Windows XP (2001). Windows comes preloaded on most new PCs, which helps to make it the most popular operating system in the world. lets see for example in the below:

2.Linux
Linux is a family of open source operating systems, This is very different from proprietary software like Windows, which can only be modified by the company that owns it (Microsoft). Linux is named after Linus Torvalds, who created the Linux kernel in 1991. The kernel is the computer code that is the central part of an operating system. lets see for example in the below:

3. Macs OS
Mac OS is a line of operating systems created by Apple Inc. It comes preloaded on all new Macintosh computers, or Macs. All of the recent versions are known as Mac OS X (pronounced Mac O-S Ten), and their specific version names are Lion (released in 2011), Snow Leopard (2009) and Leopard (2007). Apple also offers a version called Mac OS X Server, which is designed to be run on servers.lets see for example in the below:

Modern operating systems computer use a Graphical User Interface or GUI. A GUI lets you use your mouse to click on icons, buttons, and menus, and everything is clearly displayed on the screen using a combination of graphics and text. Each operating system computer's GUI has a different look and feel, so if you switch to a different operating system it may seem unfamiliar at first. However, modern operating systems are designed to be easy to use, and most of the basic principles are the same.

So important for Understanding of Operating system Computer Technology so you be know much about that and add insight about Operating System or OS..

Introduction To Computer Technology Basic

noreply@blogger.com (wawasan dunia) — Sat, 7 Jan 2012 15:36:00 -0800

Introduction To Computer Technology Basic is something that will discuss about computer technology. if you still lay here and do not know much about computer technology will, you are in the right place to acquire knowledge. Perhaps you would just like to know more about how computers work? When it comes to learning today's technology, Computer technology Basics has all the basic concepts covered. and I have discussed of the Tutorial Technology Computer if you are interested please see and read. because there I present a full and powerful . ok ok next thing I will discuss this time is :

Introduction To Computer Technology Basic # 1: What is Computer?
A computer is an electronic device that manipulates information, or "data." It has the ability to store, retrieve, and process data. You can use a computer to type documents, send email, and browse the internet. You can also use it to handle spreadsheets, accounting, database management, presentations, games, and more.

Introduction To computer Technology Basic # 2: Some Basic Of Computer Technology
Some Basic Of Computer Technology is consist of two basic parts:

Hardware is any part of your computer that has a physical structure, such as the computer monitor or keyboard.
Software is The programs (instructions) that tell the computer what to do. Some examples of software are web browsers, games, and word processors such as Microsoft Word.

Introduction To computer Technology Basic # 2: Types of Computers Technology?Types of Computers Technology consists of several kinds, computers come in many shapes and sizes, and they perform many different functions in our daily lives. When you withdraw cash from an ATM, scan groceries at the store, or use a calculator, you're using a "Type of computer Technology".

1. Personal Computer (PC)
Many people use Personal Computer (PC) at work, home, school, or the library. They can be small, medium, or large in style, and usually sit on a desk. Once you add a monitor, mouse, and a keyboard, you have what is typically known as a desktop computer. If you compare a PC and a laptop with the same features, you will most likely find that the desktop computer is priced lower. Some desktop computers have a built-in monitor to save space. These are often called all-in-one desktop computers. just look at the example below :

2. Laptop or Notebook
Laptop or Notebook is a personal computer for mobile use. A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, and/or a pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. look at the example below :

3. Netbook
Netbooks are a category of small, lightweight, legacy-free, and inexpensive laptop computers. netbooks omitted certain features. featured smaller screens and keyboards, and offered reduced computing power when compared to a full-sized laptop. Over the course of their evolution, netbooks have ranged in size from below 5" screen diagona to 12". A typical weight is 1 kg (2–3 pounds). Often significantly less expensive than other laptops. try look at the example below :

4. Macs
Macs is a series of personal computers designed, developed, and marketed by Apple Inc. it was the first commercially successful personal computer to feature a mouse and a graphical user interface rather than a command-line interface. look at the example below :

5. Server
Server is a computer that "serves up" information to other computers on a network. Many businesses have file servers that employees can use to store and share files. A server can look like a regular desktop computer, or it can be much larger. try look at the example below :

6. Mainframes
Mainframes are powerful computers used primarily by corporate and governmental organizations for critical applications, bulk data processing such as census, industry and consumer statistics, enterprise resource planning, and financial transaction processing. look at the example below :

That's part of the Introduction To Computer Technology Basic, still many things that might be lacking in this post, but you don't worry, because I've put them in my other articles and of course you will learn a lot about computer technology.

Hi all, at the begin before making this blog I've written everything I know and put it in the post, I still do not understand about the ins and outs of the story blogosphere.Her was the first time I saw my friends have a blog originally fixed I am not interested about the world of blogs . I'm really addicted to blogging, the blogosphere is very interesting too. Initially I also do not know whether you can make money through your blog. The story first time i see friends still have the first blog I'm Not Interested hell A World on the blog. In fact it turns out I'm Addicted to blogging, the word of blog as well and very exciting too.. Initially I Do not Know if through a blog can also generate money.

Since then I was looking for information on how to make money through blogs. Apparently a lot of blogs are popping. At that time I had difficulty at all to find relevant information, but I keep resolved to find what I want, finally the fruit of patience that I can also reap.

I've dabbled in a wide range of hosting on the web, do not know how much I had forgotten so much. Previously I always fail if the writing on the blog, because less consistent until all of my previous blog topic not frivolous. Well since from the lessons that I could I started to improve my writing. And was finally created this blog and hopefully I can contribute much to the needy.

When I was writing for this blog I do not really speak English, even though only a little that I know to write in English Idioms, because to write in English that can be received much more difficult people turned out.

So that's how I describes about this blog, if the delivery is less good article please corrected well, because without you this blog is nothing .. enjoy it..
