A warm welcome to the Unix and Shell Scripting course by Uplatz
What is Unix?
UNIX (or Unix) is an operating system first developed in the 1960s in the Bell Laboratories of AT&T, and has been under constant development iterations ever since. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops.
It provides its users with: program development tools; electronic communications facilities, such as an electronic mail; text editors and text formatters. There are also many development tools available as standard within the UNIX operating system that other operating systems require as add-ons.
UNIX systems also have a graphical user interface (GUI) similar to Microsoft Windows that provides an easy to use environment.
Types of Unix
There are varied versions of UNIX having common similarities but different flavors in terms of architecture and execution. The most popular varieties of UNIX are Sun Solaris, GNU/Linux, and MacOS X.
Architecture of Unix operating system
The UNIX operating system consists of three parts - a) the kernel, b) the shell and c) the programs.
The kernel of UNIX is the hub of the operating system: it allocates time and memory to programs and handles the filestore and communications in response to system calls.
The shell acts as an interface between the user and the kernel. When a user logs in, the login program checks the username and password, and then starts another program called the shell. The shell is a command line interpreter (CLI). It interprets the commands the user types in and arranges for them to be carried out.
Everything in UNIX is either a file or a process. A process is an executing program identified by a unique PID (process identifier). A file is a collection of data. They are created by users using text editors, running compilers etc.
The standard shell is the Bourne Shell which was designed for general purpose use. It is relatively small, and efficient, but lacks certain facilities such as a command history and aliasing. Two popular enhanced shells are the C Shell and the Bourne Shell. The C shell is less efficient compared to the Bourne and Korn shells, the Korn shell is larger than the Bourne shell but it is more efficient because of its built-in functions.
The shell interacts with the UNIX's Kernel which is heart of the operating system. The kernel is the bridge between the application packages and the hardware it is running on.
