## Projektgeschichte und Nutzung

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.

### Projektgeschichte

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.

### Adoptionsgeschichte

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.

### Wie es verwendet wird

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.

### Warum Paket-Nerds sich dafür interessieren

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.

### Zeitleiste
