AWK is a programming language created in the late 1970s, designed for text processing and data analysis. AWK is an acronym for "Aho, Weinberger, and Kernighan," the three designers of the language. AWK is a procedural language with a syntax that is similar to C. The program consists of a series of patterns and actions, which are each run in order. Patterns are matched against input text, and if a match is found, the associated action is executed. AWK is often used for data manipulation and reporting. It can be used to extract data from files or to create reports based on data found in files. AWK can also be used for simple programming tasks, such as calculating averages or sums.
