## Historique du projet et usages

GNU Which is the GNU implementation of the which utility, a small command that reports which executable a shell would find for a command name. Its domain is intentionally narrow: inspect command search paths and explain why a name resolves to one program rather than another.

### Historique du projet

The official Savannah project page is the package home, and the GNU FTP archive records public releases from which 2.16 and 2.17 in 2007 through later 2.x releases. After version 2.21 in 2015, GNU FTP shows renewed releases in the 2.22, 2.23, and 2.25 line during 2025 and 2026.

### Historique d'adoption

The utility is widely familiar because shells, Unix variants, and GNU systems all have command lookup workflows. GNU Which remains separately packaged for environments where users want GNU behavior, GNU licensing, or an external executable rather than a shell builtin or shell-specific type command.

### Modes d'utilisation

Practitioners use which when debugging PATH order, checking whether a package installed the expected executable, documenting build prerequisites, or explaining why scripts pick one compiler, interpreter, or helper over another.

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

The significance is mostly operational: it is a tiny diagnostic tool for path hygiene. In package-manager culture, which helps confirm shims, keg-only tools, alternatives systems, and GNU-prefixed replacements without reading shell startup files by hand.

### Chronologie

- 2007: GNU FTP archive lists which 2.16 and 2.17.
- 2015: GNU FTP archive lists which 2.21.
- 2025: GNU FTP archive lists which 2.22 and 2.23.
- 2026: GNU FTP archive lists which 2.25.

### Related projects

- Related tools include shell builtins such as command -v and type, POSIX shell command lookup, alternatives systems, and package-manager shim directories.
