Zzz

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.
