Linux - The shell ------------------------------------------------- Introduction to the shell The command interpreter is the interface between the user and the operating system‚ hence the name "shell". The shell therefore acts as an intermediary between the operating system and the user thanks to command lines that are entered by the latter. Its role consists in reading the command line‚ interpreting its meaning‚ carry out the command‚ and then return the result via the outputs. The shell

Windows and Linux Memory Management Comparison Introduction Memory management is a critical piece of both Windows and Linux computer architecture that enables the computer to allocate the physical memory available between multiple processes. Windows and Linux memory management structures and algorithms have much in common‚ such as facilitating expansion of memory address space beyond the limits of physical memory through the use of virtual memory addressing that is coordinated

today and what some consider as one of the best computer operating systems called UNIX. As years pass‚ UNIX is a widely used and influential operating system that has spawned hundreds of descendants each touting their existence will bring the demise of the mighty UNIX. Even other operating systems such as IBM’s OS/2 Warp and Microsoft Windows tried to dethrone‚ and in Microsoft’s case even today‚ the seat that UNIX has in the world of operating systems.

CHAPTER 1 History of Debian Unix/Linux UNIX has been a popular OS for more than two decades because of its multi-user‚ multi-tasking environment‚ stability‚ portability and powerful networking capabilities. In the late 1960s‚ researchers from General Electric‚ MIT and Bell Labs launched a joint project to develop an ambitious multi-user‚ multi-tasking OS for mainframe computers known as MULTICS (Multiplexed Information and Computing System). MULTICS failed (for some MULTICS enthusiasts"failed" is

Some Basic UNIX Commands NB*”Rm” The UNIX operating system has for many years formed the backbone of the Internet‚ especially for large servers and most major university campuses. However‚ a free version of UNIX called Linux has been making significant gains against Macintosh and the Microsoft Windows 95/98/NT environments‚ so often associated with personal computers. Developed by a number of volunteers on the Internet such as the Linux group and the GNU project‚ much of the open-source software

UNIX ARCHITECTURE The architecture of UNIX is divided into three levels. On the outer crust reside the Application Programs and other utilities. At the heart of UNIX‚ on the other hand‚ is the Kernel‚ which interacts with actual hardware in machine language. The stream lining of these two modes of communication is done by the middle layer called Shell. Thus the three basic layers are:- ✓ HARDWARE ✓ KERNEL ✓ SHELL At the core is the physical

UNIX File Access In order to understand how to control access to a file in a system that supports 5‚000 users to 4‚990 of those users‚ a basic understanding of the file permissions of a file on a UNIX system is necessary. A user has the ability to perform three basic actions to a file‚ read‚ write and execute. These three actions will be represented by r‚ w‚ and x respectively. A UNIX system uses a combination of these characters to control the file permissions. The first three characters represent
