Historique du projet

The upstream project is util-linux, described by its README as a collection of Linux utilities. util-linux carried the name util-linux-ng from 2006 through 2010, then continued under the util-linux name with kernel.org as the primary source location and GitHub as a backup web interface.

The util-linux NEWS file records `getopt` updates in the 2.11 and 2.13 development era, including replacement with getopt 1.1.3 by Frodo Looijaard and an update to 1.1.4. The man page identifies the command as the enhanced `getopt`, focused on parsing command options for shell procedures.

Historique d'adoption

As part of util-linux, enhanced `getopt` is part of the broad Linux userland toolbox. On macOS, Homebrew packages it as `gnu-getopt` and marks it keg-only because macOS provides BSD `getopt`; on Linux, the formula also avoids conflict with the full util-linux package. That packaging split is the main reason the Homebrew package name differs from the upstream project name.

Modes d'utilisation

Practitioners use `getopt` in shell scripts to normalize short and long options, detect invalid arguments, preserve whitespace through shell quoting, and test whether the enhanced implementation is present. The `-T` probe is explicitly documented for distinguishing this implementation from older `getopt(1)` variants.

Pourquoi les passionnés de paquets s'y intéressent

The package matters because option parsing is a portability trap in shell scripts. Installing `gnu-getopt` gives macOS and other non-GNU environments the util-linux behavior many Linux-oriented scripts expect, while Homebrew's keg-only status prevents accidental replacement of the system utility.
