It is essentially a packaged one-command wrapper around Apple's IOKit power-management APIs. ### 项目历史 The upstream README presents Zzz as a command-line macOS sleep program similar to SleepNow, with traditional make-based installation and a Homebrew installation path. The source is intentionally small C code using IOMasterPort, IOPMFindPowerManagement, and IOPMSleepSystem to ask macOS to sleep. There is little public narrative around the project beyond the README and source, so its history is best understood as preservation of a tiny utility rather than an evolving application ecosystem. ### 采用历史 Adoption appears narrow: users install it when they want a memorable terminal command that sleeps a Mac immediately, especially in scripts or shell workflows where a GUI sleep command is awkward. The README's explicit Homebrew instructions show that package-manager installation is part of the intended usage story. ### 使用方式 Usage is intentionally minimal: run Zzz, and the Mac sleeps immediately. The program has no configuration file, credentials, long-running daemon, or visible help flow; its behavior is the side effect of calling the macOS power-management sleep API. ### 为什么软件包爱好者会关心 Zzz is package-nerd significant as an extreme small-package case. It demonstrates why package indexes contain tiny platform appliances: a few lines of C plus a stable command name can be more convenient than remembering or retyping lower-level system calls or scripts. It also shows the maintenance quirks of old macOS C utilities: even a sleep wrapper depends on SDK headers, IOKit linkage, and small compatibility fixes over time. ### 时间线 - Public README era: Zzz is documented as a command-line macOS sleep program with make-based installation and Homebrew installation instructions. - Current source: Zzz implements sleep by opening the macOS power-management connection and calling IOPMSleepSystem. ### Related projects - Related tools and APIs include Apple's IOKit power-management APIs, pmset sleepnow, SleepNow-style utilities, SleepWatcher, caffeinate as the opposite keep-awake workflow, and other macOS command-line power-management helpers. ### 来源 - - - - ## 安全说明 narrow executable package without higher-risk signals. - **Geiger 风险:** 绿色 / 低 - narrow executable package without higher-risk signals ## 源数据库详情 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** zzz - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Requirements:** macos - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## 其他软件包管理器记录 - Nix - zzz: normalized package name match | nixpkgs package indexes: pkgs/by-name/zz/zzz/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - zzz - 0.2.0-r0: normalized package name match | Alpine Linux edge package indexes: zzz from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Suspend or hibernate your computer | https://github.com/jirutka/zzz - apk - zzz-doc - 0.2.0-r0: normalized package name match | Alpine Linux edge package indexes: zzz-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Suspend or hibernate your computer (documentation) | https://github.com/jirutka/zzz ## 相关链接 - [Source-control packages](https://www.automicvault.com/zh-hans/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/zh-hans/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/zh-hans/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://www.automicvault.com/zh-hans/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [powerman](https://www.automicvault.com/zh-hans/pkg/brew/powerman/) - Shares av.db curated category or tags: cli, power-management, system. - [nut](https://www.automicvault.com/zh-hans/pkg/brew/nut/) - Shares av.db curated category or tags: cli, power-management, system. - [sleepwatcher](https://www.automicvault.com/zh-hans/pkg/brew/sleepwatcher/) - Shares av.db curated category or tags: cli, macos, sleep, system. - [apcupsd](https://www.automicvault.com/zh-hans/pkg/brew/apcupsd/) - Shares av.db curated category or tags: cli, power-management, system. - [asitop](https://www.automicvault.com/zh-hans/pkg/brew/asitop/) - Shares av.db curated category or tags: cli, macos, system. - [bluetoothconnector](https://www.automicvault.com/zh-hans/pkg/brew/bluetoothconnector/) - Shares av.db curated category or tags: cli, macos, system. - [blueutil](https://www.automicvault.com/zh-hans/pkg/brew/blueutil/) - Shares av.db curated category or tags: cli, macos, system. - [brightness](https://www.automicvault.com/zh-hans/pkg/brew/brightness/) - Shares av.db curated category or tags: cli, macos, system. - [mas](https://www.automicvault.com/zh-hans/pkg/brew/mas/) - Local package facts share a topical domain.
