Bash Shell Scripting- Introduction to AWK

The video provides an introduction to AWK, a versatile programming language used as both a command and scripting language, particularly in Unix systems for text processing. It explains how AWK can be used to manipulate text by treating lines as records and fields, and discusses the syntax and options available for AWK commands. The video also covers predefined variables in AWK and how they can be used for effective scripting.
