The Linux people like to claim that the directories are actually just another file type. This statement may be misleading. We have seen in a previous article that creates a file with a file editor. We will see later in this article how to create a directory.
So what is a directory of Linux? A directory is a collection that may include one or more directories, one or more files, or in fact be empty. You can think of a file directory as a folder or notebook computer containing separator sheets (directories themselves) and pages (files.o) Like a sheet of notebook can not contain a separator, a Linux Files can not contain a directory.
Up to now take our comments on the Linux for the Windows directory. Now let’s look at some differences between these two systems. First are the naming conventions. Linux is still distinguishes between lowercase and capital letters in directory names. Microsoft Windows is not. For example, Linux is pay12june Pay12june and are like two different directories, as different as the directory and heighho pay12june. These directory names are used as file name in the preceding article. While Linux has a private directory and file names, in general we can not say the name if it is a filename or a directory name. So beware. Linux helps us here ‘command ls, which lists the contents of a given directory usually lists the files and directories in different colors.
Directories are hierarchical. They look like a tree or a tree. But unlike a tree (or Microsoft Windows), Linux has a single root. The root, designated as / is at the top instead of at the bottom of the hierarchy. Just below the root directory is several subdirectories. For example, the directory / home is a child of / root. The number and names of the subdirectories of the first level varies from one version of Linux to another. For example, some Linux distributions include a directory / root, while others do not. The root directory / (and subdirectories, are used both terms) is a child, the root directory.
The / home directory is important. E ‘divided into subdirectories, one for each user. We like to work with Damn Small Linux, a free version of Linux that runs on the Windows desktop and requires only 50 megabytes of disk space. Damn Small Linux automatically creates a user called dsl whose home directory is / home / dsl, a work area reserved mainly for this user. All versions of Linux divide the directory / home user directory according to this simple naming convention.
Linux provides several commands to process the directory. For example, the command mkdir creates a directory. The command rmdir removes a directory, but in the simplest case when empty. The cd command changes the working directory, the directory where you are. The pwd (print working directory) command displays (print) is not the working directory. Beginners should run this command frequently to reduce errors. For example, if the user of DSL, I think we are placed in / home / DSL, but are located in the / you can not save files with a single command. Why? Because they lack the necessary authorization, the subject of our next article.
Maybe domination is too strong a word. Maybe not. The market conditions for Linux are as favorable as they have ever done. Apple and Microsoft have weaknesses that are evident, or will soon be revealed.
The public is becoming more familiar with technology in general, and beginning to understand your options. There are some things that hinder the adoption of public opinion on the operating system, in my opinion. We deal with more opportunities for Linux and weaknesses that can and do slow its adoption as a mainstream operating system.
Let’s start with the environment: Microsoft is really wrong with Vista. I mean bad. They made an operating system that has closed all but the new PC market. Therefore, racks like a baby every time you need to install a program or download something, or synchronize your MP3 player. The business market will not touch it. Now, they hired Jerry Seinfeld to solve everything. Someone has to say that just because idolizes Superman, does not mean that he is Superman. Microsoft looks tired. You should probably just release an operating system called XPlus (for the uninitiated, it would be XP Service Pack 4).
Apple gaining market share and shoot at Microsoft, now worth more than Google. There are problems encountered along the path of growth. Apple has always had security and the fact that you do not need anti-virus software for their systems. My professor of computer science (in thousands of years) told me that there was no need for a simple reason: Cookies (known to the general public as “hackers”) was not very profitable to crush a MAC. The adoption rate was too low. Now that the adoption rate has increased the possibility of vicious attack fanboys bragadocious is almost irresistible. What better way to humiliate people arrogant, artistic?
Then there is the fact that Microsoft seems to be a good grandfather when it comes to openness. Steve Jobs keeps his cards close to chest ridiculous. While this may not annoy users often have the nerves of those who want total control of your system. Apple has entered Microsoft’s DRM, and has recently criticized by the invisible software updates. Does not take long for adventurers to download another OS and find other programs to meet your needs.
Linux has come a long way because of an idea of your operating system: Ubuntu. Talk all you want about Debian, Fedora and SUSE are pure nectar, Genuine Linux. Canonical’s Mark Shuttleworth has made Linux attractive to the average user. The installation process is easy, free, and the addition of programs is a breeze with Synaptic. wi-fi support much better in this distro, as is the support of the printer. It has the largest community of Linux.
That the community tends to write programs that solve very specific problems. They are writing programs that meet or exceed closed source, commercially available software. This is the most vital to the continued growth of the Linux operating system.
The security problems for Linux are almost nonexistent at the moment. It is very tight, does not mean you can not do is just that much more profitable to disrupt communication on the Internet than it is to hack a Linux system. In addition, the Linux community will monitor and make you eat your hard disk by removing one of their PC. This may change, and wider adoption, but now I’m not worried about some script kiddie hacking my Windoze box.
If this is true, then what is the way to promote the adoption of Linux?
Sound. Bet you thought I was going to say “command line”. We’ll get to later. Sound Linux is a pain to configure, and it is really horrible, if you want something more than a program that requires audio output. There are a couple of different ways to implement sound in Linux. Some of them are stable and others not. In 50% of cases, the sound of a job application, while another does not. Yesterday, I found a case where a sound server actually had a full race application. Until Linux converts sound into a single architecture, then it will keep the average user of employees. . .
The command line. We knew it was coming, I just gave notice. I like the command line, to some extent. It allows me to instantly kill a program when it freezes, no questions asked. I can modify configuration files without opening a text editor. Just today, an article that appeared on my screen, where the author says you can use Linux without touching the command line. While technically true, that statement is misleading at best. All items Help Forum started with Linux, or are supposed to have opened the command line. If you need to fix something, you use the CL, or not using Linux for a long time.
This is something that people are forced to agree with, unless the Linux kernel and sources of the library is closed. What I hope happens is a line of integrated access commands in different windows manager as the default setting. Intuitive controls (and the ability for users to disable this feature) should play a larger role in the launch for the average user. The final robbery. . .
Developers, developers, developers. So laugh with Steve “MonkeyBoy” Ballmer in an explosion of “irrational exuberance.” leading developers of closed source software gets on board for the full adoption of Linux. While I like the GIMP, and devoted enormous, I miss the amazing ability to batch process and clear interface of Photoshop CS3 (GIMPshop is not necessary). I thought it was. I miss Flash. I do not want dual boot, or using WINE. I want a solution to run natively. This is what is currently missing, the equation of Linux. I want a peanut butter sandwich is not a bologna sandwich. Just because you can eat, not to say that I love you. The common Windows user feels a fear far greater than I can do about it and no waiver programs your family and your operating system without a serious fight.
For each default, Linux has thousands of advantages. Linux will become a major player in the operating system is (and is) the largest bridge in the software platform independent road and cloud computing. Maybe. The question is how soon is true, as the Linux community, stop arguing about which distribution is better, and have a conversation about which way to take for the domain as an operating system.
