Now, when many people are getting started with computers, they should see Windows 98.
To be honest, 98 is already a very user-friendly and encapsulated system.
Anyone who knows nothing about computers can use it quickly. In this way, many
The impression of "computer" is as bad as those who first came into contact with me.
. In the DOS era, if you do not understand basic computer knowledge, do not play
It's not like many people do not know what the CPU is, but it can be flash
Master, dumping numerous mm. If you are such a person, you want to learn Linux, you have
Going back, why?
Let's first look at the development of Ms operating system, he has two sets of kernel MSDOS-DOS + win3.2win9x/
-WINXP
Windowsnt3.1 --- nt4.0win2000/his development is from the DOS character-only interface system to a character Interface
And an image interface application (win3.2 ).
Win95 is integrated, and now, at the beginning, the nt of the graphic interface becomes
Windows XP, his ambition in the future is to become. net on the Internet. Now let's look at Linux. Linux is just a kernel! This is important. You must
Understand this.
Only one kernel cannot constitute one operating system. Current Linux operating system
Such as RedHat, blue dot, and red flag all use such a kernel.
Composed of applications (including X. Anything called an operating system is
In this way: Kernel + User Interface + general application. Now I will take the correspondence between the MS system and the Linux system to make everyone more
Know Linux. If you have installed dos, you must know that the entire hard disk is like this after the installation is complete.
The root directory contains
Io. sys msdos. sys command.com config. sys autoexec. bat
A total of five files and the C:/DOS directory are very simple. Where
Io. sys and msdos. sys are the system kernel, while command.com is the user interface (Shell ),
Config. sys and autoexec. Bat are configuration files, and the C:/DOS directory contains general applications.
When the system starts, first Mount Io. sys, And then mount msdos. sys and
Command.com, and then a prompt appears. Now you can enter the command. For example
Copy C:/aaa.txt D:/aaa.txt to copy the file. You can also use
Some applications to complete the work, such as editing files with edit, and writing basic programs with QBASIC.
Next, you have installed a program called foxpro2.6, which allows you to do some
For database work, you have installed a program named Windows Chinese version.
This program is amazing. You don't need to execute commands in the command line now. You can use the mouse
Open File Manager, Open C, open another window d, and pull it with the mouse
Copy C:/aaa.txt D:/aaa.txt.
It is no different from Windows 98. OK, after goto Linux is installed
The root directory contains boot, bin, sbin, etc, usr/bin, and other directories.
There is a vmlinuz file under boot. This is the kernel, which is the most powerful hacker in the world.
The stuff that Linus writes first.
There is SH in Bin. This is shell (= command.com, user interface)
This is because there is no internal command in UNIX systems.
/Bin +/sbin = command.com
And/etc = config. sys + msdos. sys
Remaining/usr/bin = C:/DoS
Of course. Because Linux is much larger than DOS, reahat and red flag may have different arrangement methods,
There are no rules for things in various directories.
When Linux is started, it loads vmlinuxz and SH (or other shells, such as Bash ),
Prompt. Now you can enter the command. For example
CP/aaa.txt/tmp/aaa.txt. You can also use VI to edit files and use GCC to compile programs.
Next, you have installed a program called MySQL, which allows you to do some
Database work, and then you install a program named kde4.0, which is amazing
Now you don't have to execute commands in the command line. You can use the mouse to open the file manager,
Open/open another window/tmp, and click the mouse to complete CP/aaa.txt/tmp/aaa.txt
This command, you just moved the index finger a few times and now in Windows 98 is no different. I hope you can understand why I say you are turning back,
Because the current Linux operating system = win3.2 of MS
However, the MS system has gone through 9x and is now XP, which lags behind two generations. Of course, this is from the user interface, but it is precisely because many people have installed a Linux system and are engaged in the east and west on the KDE of X, and nothing else can be done, why can't you do it? Because you haven't done dos, you don't even know that the system can do this. At first, you came into contact with 98. The computer gave you the feeling that you were operating with the mouse. You think that is also an operating system, and Linux should be like this. You didn't even think that you always thought you were playing Linux, But what you actually played was just a Linux system running
.
Therefore, many people have completed installation for a few days, but Linux does. This can be said to be true or not.
Linux, you haven't even seen what it looks like. What do you have to say about it?
But KDE does. You have used 98. Now you can use 3.2 to see what you have.
Feeling? In terms of stability, I don't get 98, take 95, if the same job, 95 crashes once a day
Then X will crash 10 times, if it is 2000, 2000 will crash once a day, and X will crash 100 times.
It is similar to 3.2. But why do I still hear that some Hollywood movie stunt effects are on Linux?
What is done? To attend an important banquet, you can buy a famous suit or order one.
Set, customized, of course, better fit, but the price is more expensive, the workload is also greater
Brand name suit = Windows
Customized suit = Linux system + modify system kernel + modify x code + modify KDE code + specially written stunt software the suit you are now wearing is a street goods, that is, the reahat garment factory is designed to adapt to mass production of all people around the world.
Do you understand? If you understand that Linux is better than windows, I don't need to talk nonsense. Why does Linux tend to be related to hackers?
I remember reading a book saying, "Linux is a hacker named Linus and many hackers on the Internet.
Written together ". So how can a system written by hackers be irrelevant to hackers?
Of course, this definition of "hacker" is totally different from the definition of "hacker" in the hearts of many Chinese people.
The former has almost never intruded into other systems, and the latter has intruded into other systems. If you are an artist, you are also using computers almost all the time except sleeping. You are always using Photoshop to do this. In the art industry, you are also a master in this industry. But you don't care about what you do, how the computer actually helps you. Computers are just a tool you have created. It is like music that many people like to listen to, but you don't care about the music you hear at all. From the original singer's mouth, she came to be appreciated by you. But for an hifi enthusiast, all she cares about is this. Now I have just mentioned the copyscript command. For a hacker, she doesn't really care about aaa.txt.
In this file, what does the computer do during the process from C:/aaa.txt to D:/aaa.txt? Now let me ask the person who is reading this post: You must have done this thing by copying a file from one place to another, right? But when you do this, have you ever thought about how the computer completes your operation? If your answer is: Oh, I have never really thought about it ~~
So, you don't have the talent of hackers at all, and you still have a bright future for easy mixing.
Root-sourcing is the nature of hackers. In this regard, Linux can satisfy the requirements, but Windows cannot,
Press copy C:/aaa.txt D:/aaa.txt on DOS. The task of copying is completed, but do you know what the computer has done?
You can only judge how the system is completed based on your experience. You cannot determine whether your judgment is correct until you have read the source code of copy. However, the source code of CP on UNIX is basically ready for use.
For TCP/IP, linxu allows you to hack into the kernel, but for Windows, you can only hack into Winsock.
You can clearly understand the specific communication between APACHE and the system, but you cannot know the communication between IIS and the system.
The relationship between Linux and hackers is here, and there is nothing to do with intrusion. Many remote vulnerability attack programs need to be compiled on Unix systems, which is correct, but the original meaning of those programs is to give an example to make you optimistic about it. If you understand it, the change can also be compiled on win. Unix has many advantages over windows, and there are too many things worth doing. I just can't tell you what you love when you love someone, what is she worthy of your love?
However, windows is not spam. It is definitely not used as a tool. It is hundreds of times better than UNIX.
It seems that you should now understand why many remote vulnerability attack programs are written in UNIX format, because they are quite familiar with the system because they can discover this vulnerability, moreover, Unix makes him quite familiar with the system. He does not consciously use Unix. However, however, most of the Code is written by using ultraedit in windows. It seems that I am away from the question. I want to give some suggestions to my friends who want to learn Linux (UNIX), but I have said this,
But I don't think there is a problem. I hope you can see what I want to give you.
1. determine the significance of Linux to you based on your current level.
2. Are you sure you are playing Linux instead of X
3. Unload the X system and install the source code for the remaining space.
4. Do not use the rpm-I Method to install the program.
5. Find a common Telnet software. I recommend securecrt.
6. If you only have one computer, install VMware and use this method to access Unix
7. Read the post again and try again to understand the hidden suggestions in my post.
8. In the process of learning Linux, write down the experience that has been played by Linux.
9. How can I remember the interesting things about Linux during Linux?
