AWK (/ ɔː k / [4]) is a domain-specific language designed for text processing and typically used as a data extraction and reporting tool. Like sed and grep , it is a filter , [ 4 ] and it is a standard feature of most Unix-like operating systems .
The AWK Programming Language [1] is a well-known 1988 book written by Alfred V. Aho, Brian W. Kernighan, and Peter J. Weinberger and published by Addison-Wesley, often referred to as the gray book. [2] The book describes the AWK programming language and is the de facto standard for the language, written by its inventors. W.

Regular expressions are used in search engines, in search and replace dialogs of word processors and text editors, in text processing utilities such as sed and AWK, and in lexical analysis. Regular expressions are supported in many programming languages. Library implementations are often called an "engine", [4] [5] and many of these are ...
sed ("stream editor") is a Unix utility that parses and transforms text, using a simple, compact programming language. It was developed from 1973 to 1974 by Lee E. McMahon of Bell Labs, [1] and is available today for most operating systems.
awk – used for text file manipulation. sed – parses and transforms text; SQL – has only a few keywords and not all the constructs needed for a full programming language [a] – many database management systems extend SQL with additional constructs as a stored procedure language
