## Historique du projet et usages

has is Kiran Dabir's dependency-free Bash utility for checking whether named command-line tools are on `PATH` and reporting their installed versions.

### Historique du projet

The official GitHub repository was created in February 2014. The project stayed centered on one portable Bash script while accumulating tool-specific version detection, readable success and failure output, meaningful exit status, and project-local `.hasrc` files.

A tagged GitHub release series is visible from v1.2.0 in 2018 through v1.5.2 in August 2025. The README continues to present direct download and execution as first-class options alongside package managers.

### Historique d'adoption

has spread through several conventions favored by shell users: direct `curl` execution, a copied script on `PATH`, Git installation, Homebrew, asdf, and mise. Supplied metadata also records Homebrew and Nix packages.

### Modes d'utilisation

Users run commands such as `has node npm java git`; the output lists detected versions, and the exit status counts missing commands. A project can commit one tool name per line in `.hasrc`, letting `has` serve as an immediately readable environment preflight for developers and scripts.

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

has is a strong example of the single-file shell package: no runtime beyond Bash, directly inspectable source, multiple install methods, and behavior useful both interactively and in automation. A committed `.hasrc` also acts as a lightweight executable declaration of a repository's external toolchain.

### Chronologie
