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 non-interactive Unix command grep was inspired by a common special use of qed and later ed, where the command g/re/p performs a global regular expression search and prints the lines containing matches. The Unix stream editor, sed implemented many of the scripting features of qed that were not supported by ed on Unix. [6] [failed ...
