awk



AWK is a programming language designed for text processing and typically used as a data extraction and reporting tool. It is a standard feature of most Unix-like operating systems.

The AWK language is a data-drivenscripting language consisting of a set of actions to be taken against streams of textual data – either run directly on files or used as part of a pipeline – for purposes of extracting or transforming text, such as producing formatted reports. The language extensively uses the stringdatatype, associative arrays (that is, arrays indexed by key strings), and regular expressions. While AWK has a limited intended application domain and was especially designed to support one-liner programs, the language is Turing-complete, and even the early Bell Labs users of AWK often wrote well-structured large AWK programs. AWK was created at Bell Labs in the 1970s,and its name is derived from the surnames of its authors—Alfred Aho, Peter Weinberger, and Brian Kernighan.

Introduction to Data Structures

Visit My Data Structure Blog for Programs... It is important for every Computer Science student to understand the concept of Information and how it is organized or how it can be utilized. If we arrange some data in an appropriate sequence, then it forms a Structure and gives us a meaning. This meaning is called Information . A data structure is a particular way of storing and organizing data in a computer so that it can be used efficiently. Data may be organized in many different ways. The logical model of a particular organization of data in a computer is called data structure. The choice of the model based on two considerations. It should be reflect the data in the real world. It should be simple that one can effectively process the data when necessary. E.g. Array, linked list, stack, queue, tree, graph Data structure can be classified into two: Linear: A data structure is said to be linear if its elements form a sequence E.g. Array, linked list, stack, queue Non-Linear: A dat

Basic Linux Commands For Beginner's

Basic Linux Commands for Beginners Linux is an Operating System’s Kernel. You might have heard of UNIX. Well, Linux is a UNIX clone. But it was actually created by Linus Torvalds from Scratch. Linux is free and open-source, that means that you can simply change anything in Linux and redistribute it in your own name! There are several Linux Distributions, commonly called “distros”. A few of them are: Mint Ubuntu Linux Red Hat Enterprise Linux Debian Fedora Kali Linux is Mainly used in Servers. About 90% of the Internet is powered by Linux Servers. This is because Linux is fast, secure, and free! The main problem of using Windows Servers are their cost. This is solved by using Linux Servers. Forgot to mention, the OS that runs in about 80% of the Smartphones in the World, Android, is also made from the Linux Kernel. Yes, Linux is amazing! A simple example of its security is that most of the viruses in the world run on Windows, but not on Linux
