Commands and aliases

  • fex

history

Project history and usage

fex is a small command-line field extractor for tokenizing strings and selecting fields with concise delimiter and range syntax.

Project history

Jordan Sissel published the official fex project page on May 19, 2010, describing it as flexible token-field extraction and documenting examples for logs, paths, and passwd-style records. The GitHub repository identifies the project as flexible field/token extraction and has been public on GitHub since 2011.

Adoption history

Homebrew packages fex as a stable formula at version 2.0.0. Its official project page directs release downloads to GitHub, making the GitHub repository the practical source and release surface for package maintainers.

How it is used

Typical use is pipeline text processing: provide delimiters and field selectors to pull fields from log lines, paths, or colon-separated records. The official docs position it as a concise alternative to repeated cut or awk invocations for selected field extraction.

Why package nerds care

fex matters to CLI package users because it sits in the classic Unix text-filter niche: tiny executable, no service state, and a focused syntax that makes package-manager installation convenient for shell pipelines.

Timeline

  • 2010: Official fex project page published.
  • 2011: GitHub repository created.
  • 2021: GitHub repository last pushed according to GitHub metadata.
  • 2026: Homebrew formula reports stable version 2.0.0.

Related projects

  • The README says fex is related to cut, awk, and ksb's xapply field extraction syntax.
