## Historique du projet et usages

bar is a small Bourne-shell utility that behaves like cat while showing an ASCII progress bar, aimed at portable Unix installation and scripting contexts.

### Historique du projet

Henrik Theiling's project page frames bar as deliberately minimal shell code that needs no compilation and works across sh, ash, ksh, zsh, bash, and related Bourne-style shells. The design goal is portability first: when progress display cannot be supported safely, the script is intended to fall back toward plain cat behavior.

The upstream change log records a compact evolution from version 1.0's initial release through 1.1 percentage and terminal-width support, 1.2 robustness fixes across shells and systems, 1.3 feature additions such as ETA and configurable sizing, and 1.4 bug fixes.

### Historique d'adoption

bar's adoption is narrow but very Unix-shaped: it appears in Homebrew, Debian, Ubuntu, and Nix package metadata as a tiny helper for shell scripts rather than as a large standalone application.

### Modes d'utilisation

The typical use is to pipe or copy data while presenting a text progress indicator in an install script or other shell workflow. Its upstream page emphasizes embedding or reusing the script body in portable installers.

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

bar is interesting because it solves a common packaging-era problem without a compiled dependency, curses UI, or modern shell assumptions. It is the sort of small, old-school utility that package managers preserve because it remains useful in constrained Unix environments.

### Chronologie

- Version 1.0: Initial beta release.
- Version 1.1: Adds percentage display and terminal-width detection.
- Version 1.2: Focuses on robustness across Bourne shells and operating systems.
- Version 1.3.1: Adds ETA, quiet mode, size overrides, and script-dumping features after a broken 1.3 prerelease.
- Version 1.4: Stable bug-fix release.

### Related projects

- bar overlaps with cat, dd, pv, and shell progress-bar snippets, but its upstream niche is stricter portability and embeddability in Bourne-shell install scripts.
