## What is Awk?
|
||||
Awk (also written as awk and AWK) is a programming language used for text processing and typically used as a data extraction tool. Awk comes with most UNIX-based operating systems, and also with some other operating systems, such as Windows 95/98/NT.
|
||||
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**.
|
||||
|
||||
An awk program is a sequence of pattern-action pairs, it reads the input a line at a time and the line is scanned for each pattern in the program and if positive, it performs the associated action. Awk can be used interactively or from script files.
|
||||
|
||||
## Hello World in Awk
|
||||
|
||||
```awk
|
||||
BEGIN { print "Hello, world!" }
|
||||
```
|
||||
The Code is self explanatory , the **BEGIN** keyword denotes the beginning of a awk program.
