Both operating systems are fundamentally different in their design and operation. Linux is an open-source derivative of Unix. Windows is the most prominent proprietary operating system, while Linux is the most prominent operating system that is free software. Unix has a two-user model. There is the root user, everything is allowed, and all other users, whose rights are severely restricted. A user must perform actions that require extended rights, he may do so only if the rights of the user gets root. This is also still the case and leads to considerable difficulties in the implementation of computer security concepts.

The first non-MS-DOS-based Windows NT 3.1 was in the years 1988 to 1993 from Microsoft Windows NT got different security architecture than UNIX. Even Windows has a powerful user named SYSTEM. However, it is not possible to register under that name. All other users have different global rights. An administrator who attempts to access a file, for which he does not have the authorization, you, like any other user, an error message. However, he has the right to file on his property make. This can be done easily via the Windows Explorer. Then he can even assign permissions and the file to use as desired.

Windows must boot from a primary partition. Linux can boot from either a primary partition or a logical partition inside an extended partition. Windows must boot from the first hard disk. Linux can boot from any hard disk in the computer. Other users without administrator rights to self-directories can be assigned. If a user the right to “take ownership” for a directory including all subdirectories that time. That is not possible under Linux. Basically, Microsoft has in the development of Windows NT recognized that the superuser model of UNIX for modern distributed computing systems is to be kept simple.

By all the above discussion, we can conclude that Linux is far better than Windows operating system. Linux have better network and processing capabilities. For server user, home or desktop user, Linux is much cheaper as compared to Windows operating system. Microsoft allows a single copy of Windows to be used on only one computer but we can run Linux on any number of computers without any additional charges. Linux as having an extremely enhanced security and lesser chances of exploits as compared to Windows.

The final step of Linux boot process is init process, which starts a system process defined in /etc/ initab file. init config file then directs the init process and the shell script /etc/rc.d/rc.sysinit runs. Linux distros put some startup scripts in rc subdirectories, particularly at /etc/rc.d to take control of the services required to be started at boot. But sometimes, you find errors while this process and your system fails to boot. In such situations, you might need to reformat and reinstall the system. Consequently, you require your recent data backup to restore missing information. But if backup exists in unclean state or is currently not present, use of Linux Data Recovery applications can get your lost data back.

You might receive the similar error message while trying to boot your Linux based system:

“/etc/init.d/rc exited outside the expected code flow.

init:rcS main process <number> terminated with status <status>”

You cannot boot the system after this error message.

Cause

Init scripts are located at /etc/init.d/ directory. The above error message occurs if these scripts fail to load and start. It might occur if some of the init.d scripts are corrupted or damaged. As a result, services don’t start and your system fails to boot.

Solution

To solve the existing issue, you should try any of these methods:

• You can boot the system using Live CD and recreate the damaged files using gedit. gedit is the text editor developed for GNOME desktop environment. It is a UTF-8 compatible text editor.

• Try booting the system with Live CD and replacing the damaged script file

• If the above measures fail to correct the problem, you should reformat and reinstall the operating system. After this, you need to use your recent data backup to restore lost information.

While restoring data from backup, if you find any errors or it proves to be incomplete, you should use Linux Recovery applications. These are advanced tools built with indigenous technology to locate the missing information on disk and finally restore it. You find such Linux Data Recovery products with graphically rich user interface.

Stellar Phoenix Linux Data Recovery is an advanced tool to recover lost data from Ext2, Ext3 and ReiserFS based drives. It is a read-only application with high-end scanning algorithms and self-descriptive interface. It supports safe Data Recovery Linux for all of the Linux distributions like SUSE, Gentoo, Mandrake, Debian and more.

Linux people like to claim that directories are really just another type of file. This statement can be misleading. We saw in a previous article that you create a file using a file editor. We will see later in this article how to create a directory.

So just what is a Linux directory? A directory is a collection that may include one or more directories, one or more files, or in fact be empty. You may think of a directory as a computerized file folder or loose-leaf notebook that contains dividers (themselves directories) and pages (files.) Just like a notebook page may not contain a divider, a Linux file may not contain a directory.

Up to now our comments about Linux directories hold for Windows directories as well. Now let’s take a look at some differences between these two systems. First come the naming conventions. Linux always distinguishes between lower-case and upper-case characters in directory names. Microsoft Windows does not. For example, Linux treats pay12june and Pay12june are as two different directories, as different as the directories pay12june and heighho. These directory names were used as file names in the previous article. While Linux does have some reserved directory and file names, in general one cannot tell by the name whether it is a file name or a directory name. So be careful. Linux helps you out here ‘ the ls command that lists the contents of a given directory usually displays files and directories in different colors.

Directories are hierarchical. They resemble a tree or a family tree. But unlike a tree (or Microsoft Windows) Linux has only one root. The root, designated as / lies at the top, rather than at the bottom, of the hierarchy. Right underneath the root directory you will find several subdirectories. For example, the /home directory is a child of / the root directory. The number and names of the first-level subdirectories vary from one version of Linux to another. For example, some Linux distributions include a /root directory while others do not. The /root directory (or subdirectory, both terms are used) is a child of /, the actual root directory.

The /home directory is an important directory. It is 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 working area essentially reserved for this user. All Linux versions subdivide the /home directory into user subdirectories according to this simple naming convention.

Linux provides several commands to process directories. For example, the mkdir command creates a directory. The rmdir command removes a directory, but in the simplest case only when it is empty. The cd command changes the working directory, the directory in which you are positioned. The pwd (print working directory) command displays (not prints) the working directory. Beginners should run this command often to reduce errors. For example, if you, the dsl user, think that you are positioned in the /home/dsl directory but in fact are positioned in the / directory you won’t be able save your files with a simple command. Why? Because you lack the requisite permission, the subject of our next article.
