New page

Linux AWK is a language for processing text files. AWK is typically used as a data extraction and reporting tool. It is a standard feature of most Unix-like operating systems. It consists of a set of actions to be taken against streams of textual data for purposes of extracting or transforming text, for eg: producing formatted reports. The language uses the string datatype, associative arrays, and regular expressions.

AWK was created at Bell Labs in the 1970s and its name is an acronym derived from the surnames of its authors—Alfred Aho, Peter Weinberger, and Brian Kernighan.

In this series, we would mainly concentrate on how to use the wide variety of AWK commands of Linux, to handle files, directories, processes etc. These tutorials are created using Ubuntu version 16.04 and above. Please see the associated text box of individual spoken tutorials on the website to decide the versions of Linux OS to which it is applicable.

The Spoken Tutorial Effort for Linux is being contributed by Antara De, Praveen S and Nancy Varkey.
