Features of Unix | Unix Operating System | Computer Bot

The General and Additional Features of UNIX operating system are :

File and Process

File and process are two entities that are supported by UNIX A file contains information, such as text, code or directory structure that you need to save in the computer. The file is stored in the hard disk of the computer at a particular location, which can be easily remembered whereas a process is the name given 10 a file or a program that is currently running UNIX provides various tools that enable you to control a pra change the sequence of the process, and all the process.

Multi-User System

UNIX supports multitasking system as the kernel is designed to handle multiple processes. A single ser can run multiple processes simultaneously. For example, an end user can print a file and edit another file simultaneously The kernel handles the multiple processes as foreground and background processes The current process runs in the foreground and the other processes run in the background. The foreground and background processes can be switched according to the requirements. This multitasking feature is an advantage for the programmers as they do not have to close the editor and run the program; this can be done simultaneously.

UNIX Toolkit

The UNIX toolkit provides various tools that enable you to perform different tasks in UNIX as kernel alone perform every task. The tools that are included in the UNIX toolkit are:

      • General purpose tools, such as vi editor.
      • Text manipulation utilizes filters that are used to retrieve the output from two or more commands simultaneously.
      • Compiler and interpreter.
      • Network administration and system tools, such as mailx and pine.

Pattern Matching

UNIX supports pattern matching feature that enables you to retrieve the output according to the required pattern. Pattern matching in UNIX can be implemented using a special characters, such as known as metacharacter. The character denotes multiple characters. For example, if you need to retrieve all the files whose name start with A, you can give the argument for the list command as A. instead of specifying all the names of the files.

Programming Facility

UNIX provides a programming facility known as shell that is developed specifically for programmers and not for the users. The shell programming includes all programming features such as variables, loops, and control structures that help you to create a shell script.
