awk
Awk is a powerful pattern-scanning and processing language designed for efficient text manipulation on Unix-like systems. It reads input line by line, applies a set of user-defined patterns, and executes corresponding actions on matching lines, making it ideal for data extraction, reporting, and…

- Problem solved
- Awk was created to bridge the gap between simple command-line tools like 'grep' and 'sed' and writing full-fledged C programs for complex text processing. Before awk, extracting and manipulating structured text data (e.g., log files, tabular reports) from files required either convoluted shell-script pipelines of existing tools or time-consuming custom C code. Awk provided a concise, programmable solution with built-in features for record and field parsing, pattern matching, and C-like procedural actions, dramatically speeding up data manipulation tasks.
