Unix and Shell Scripting

AT&T Bell Labs released an operating system in 1960s called Unix written in C, which allows quicker modification, acceptance, and portability. A variation of Unix came in the form of Linux. It is the software on a computer which enables applications and the users to access the devices on the computer to perform some specific function. The unique features of Unix include: Multi-user, multitasking operating system, and can be used as the master control program in workstations and servers. A Kernel is at the nucleus of a computer. It makes the communication between the hardware and software possible. A shell takes input from you in the form of commands, processes it, and then gives an output. It is the interface through which a user works on the programs, commands, and scripts. The output or the result is thereafter displayed on the terminal. In Unix, the Command Shell is the native command interpreter. It provides a command line interface for the users to interact with the operating system. The script is a series of commands that will be run together.
