CLI text processing with GNU awk

Learn GNU awk is an example-based book and practice repository dedicated to mastering GNU awk for command-line text processing. It teaches the language through hundreds of short demonstrations rather than relying mainly on abstract syntax descriptions. Readers learn how awk can select records, work with fields, transform text, apply regular expressions, and build reusable processing commands. More advanced material develops progressively from the same practical style. The repository includes example files and code snippets so commands can be reproduced locally. Exercises test each major concept, and complete solutions are supplied in a separate document. An interactive TUI application also provides a hands-on way to practice selected exercises.
