GNU AWK (gawk) is the GNU implementation of the AWK programming language, a powerful open-source utility for text processing, pattern scanning, and data manipulation. It enables developers, system administrators, and data engineers to efficiently extract, transform, filter, and analyze structured and semi-structured data using concise scripts.

• Provides associative arrays, built-in functions, and user-defined functions.
• Performs data extraction, transformation, aggregation, and reporting.
• Integrates seamlessly with shell scripts and Unix command-line tools.
• Supports POSIX-compliant AWK features with GNU-specific enhancements.
• Ideal for system administration, DevOps automation, ETL pipelines, and data analysis.
