# AWK
AWK is a programming language for text processing and extraction. It is a standard [Unix](unix.md) tool included in the [POSIX](posix.md)
standard. Its name comes from the first letter of the surnames of its creators.

## Implementations
- [One True AWK](https://github.com/onetrueawk/awk): the reference AWK implementation as described in the official AWK reference manual,
supports [Unicode](unicode.md) ([UTF-8](utf8.md)) and [CSV](csv.md).
- [GNU](gnu.md) AWK (gawk): bloated, turns AWK into a full-blown programming language with supports for sockets and internationalization.
- [BusyBox's](busybox.md) AWK: small, for embedded systems use; supports some extensions from gawk.
- goawk: implementation of AWK in [Go](go.md).
