About:
Pk is a command-line utility for extracting fields from text streams, similar to the Unix cut command but with a more intuitive syntax. It allows users to specify fields by name from delimited data, making scripts more readable and maintainable. The tool is particularly useful for processing structured text like CSV or log files without complex awk or sed patterns.
Key Features:
  • Named field extraction using column headers
  • Simple, intuitive syntax compared to cut/awk
  • Handles various delimiters including commas, tabs, and spaces
  • Lightweight and fast for stream processing
Use Cases:
  • Extracting specific columns from CSV files in shell scripts
  • Parsing log files to isolate relevant fields for analysis
  • Quick data filtering in command pipelines
Alternatives:
  • cut – Standard Unix tool but requires numeric field positions and lacks named field support
  • awk – More powerful but has steeper learning curve and heavier syntax for simple field extraction
  • csvkit – Full CSV toolkit with more features but larger dependency footprint
