history

Project history and usage

pk extracts and rearranges fields from text streams.

Project history

John Morrow developed pk as a field extractor positioned between cut and awk. Its copyright notice begins in 2012.

Adoption history

The supplied source_facts.package-manager records Homebrew availability; the README also documents building and installing through Cargo.

How it is used

Pipe command output into pk and select numbered fields or ranges. Options control delimiters, quoting, empty fields, and output separators.

Why package nerds care

It follows the Unix tradition of small pipeline utilities, offering more delimiter handling than simple column selection requires without demanding an awk program.

Timeline

2012: Beginning of the copyright period recorded by upstream.

Related projects

cut and awk are the upstream project's stated comparison points.
