history
Project history and usage
Zzz is a small macOS command-line program that asks the operating system's power-management service to put the machine to sleep immediately.
Project history
The project's manual page is dated 11 August 2011 and describes a single-purpose system utility authored by David Parsons. The upstream C source remains intentionally small: it locates the IOKit power-management service, calls `IOPMSleepSystem`, reports errors, and exits.
Adoption history
The official README documents both traditional make-based installation into `/usr/local/bin` and Homebrew installation. This positions Zzz as a compact packaged convenience for shell users rather than a larger application or daemon.
How it is used
Run `Zzz` with no arguments to request immediate sleep. The manual documents a zero exit status on success and a nonzero status on failure; no root access is required.
Why package nerds care
Zzz is a characteristic micro-utility: a stable, memorable command packages a platform API call that would otherwise require custom C code or a less discoverable system workflow. Its makefile, manual page, C source, and Homebrew path exemplify the durable Unix packaging of tiny native tools.
Timeline
- 2011-08-11: The Zzz manual page documents the macOS sleep command.
- Later upstream README: Traditional make installation and Homebrew installation are documented side by side.
Related projects
- The README compares Zzz with SleepNow, while its implementation directly uses Apple's IOKit power-management interfaces.
