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. ### 採用の歴史 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. ### 使われ方 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. ### パッケージ好きにとっての重要性 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. ### タイムライン - 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. ### ソース - - source_facts.description - source_facts.package-manager ## セキュリティノート generalized runtime or code generation signal. - **Geiger リスク:** yellow / 中 - generalized runtime or code generation signal ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** bar - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** yes - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 他のパッケージマネージャ記録 - Debian apt - bar - 1.11.1-4: normalized package name match | Debian stable package indexes: bar from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Show information about a data transfer - Nix - bar: normalized package name match | nixpkgs package indexes: pkgs/by-name/ba/bar/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - bar - 1.11.1-4: normalized package name match | Ubuntu 24.04 LTS package indexes: bar from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Show information about a data transfer ## 関連リンク - [Secret-risk packages](https://www.automicvault.com/ja/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/ja/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/ja/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/ja/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [fish](https://www.automicvault.com/ja/pkg/brew/fish/) - Shares av.db curated category or tags: cli, developer-tools, scripting, shell. - [xonsh](https://www.automicvault.com/ja/pkg/brew/xonsh/) - Shares av.db curated category or tags: cli, developer-tools, scripting, shell. - [zsh](https://www.automicvault.com/ja/pkg/brew/zsh/) - Shares av.db curated category or tags: cli, developer-tools, scripting, shell. - [aliae](https://www.automicvault.com/ja/pkg/brew/aliae/) - Shares av.db curated category or tags: cli, developer-tools, shell. - [checkbashisms](https://www.automicvault.com/ja/pkg/brew/checkbashisms/) - Shares av.db curated category or tags: cli, developer-tools, shell. - [desk](https://www.automicvault.com/ja/pkg/brew/desk/) - Shares av.db curated category or tags: cli, developer-tools, shell. - [fizsh](https://www.automicvault.com/ja/pkg/brew/fizsh/) - Shares av.db curated category or tags: cli, developer-tools, shell. - [mcfly](https://www.automicvault.com/ja/pkg/brew/mcfly/) - Shares av.db curated category or tags: cli, developer-tools, shell. ## Combined YAML source View the package source record on GitHub.
