+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.

+supports [Unicode](unicode.md) ([UTF-8](utf8.md)) and [CSV](csv.md).
+- GNU AWK (gawk): bloated, turns AWK into a full-blown programming language with supports for sockets and internationalization.
+- [BusyBox's] AWK: small, for embedded systems use.
+- goawk: implementation of AWK in [Go](go.md).
