pawk is a command-line text processing utility that brings Python expressions and statements to AWK-style workflows.
It reads from standard input and lets you filter, transform, and summarize line-oriented data using Python syntax, making it useful for shell pipelines, ad hoc analysis, and quick text manipulation tasks where Python’s data structures and modules are more expressive than traditional AWK.
This is free and open source software.
Key Features
- Processes input line by line using Python expressions or statements.
- Supports AWK-like pattern matching and field-based text processing.
- Provides begin and end blocks for initialization and final output.
- Can use the first row as named header fields for subsequent rows.
- Automatically imports referenced Python modules, with optional explicit imports.
- Supports whole-file processing through end-block access to accumulated input.
- Offers configurable input, output, and line delimiters.
- Includes an option to modify files in place.
- Requires Python 3.7 or later.
