## Historique du projet et usages

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

### Historique du projet

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.

### Historique d'adoption

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.

### Modes d'utilisation

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.

### Pourquoi les passionnés de paquets s'y intéressent

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.

### Chronologie

- 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.
