{{language|AWK}}'''AWK''' is an extraction and reporting language that is designed for processing text-based data, either in files or data streams. AWK is an example of a scripting language that extensively uses the string datatype, associative arrays (that is, arrays indexed by key strings), and regular expressions. The power, terseness, and limitations of AWK programs and [[sed]] scripts inspired Larry Wall to write [[Perl]]. Because of their dense notation, all these languages are often used for writing one-liner programs. |

The awk utility is a data extraction and reporting tool that uses a data-driven scripting language consisting of a set of actions to be taken against textual data (either in files or data streams) for the purpose of producing formatted reports.
The language used by awk extensively uses the string datatype, associative arrays (that is, arrays indexed by key strings), and regular expressions.
The reference implementation is still maintained by Brian Kernighan (the "K" in AWK).
