项目历史

Fred Hucht's pstree began as a shell script in the early 1990s. The first C version dates to 1992, and the source was managed in RCS from 1994. It was formerly distributed from the University of Duisburg-Essen through FTP and a project webpage; in 2022 the project moved to GitHub.

采用历史

The implementation was designed for portability across Unix systems. Its official README lists AIX, Linux, HP-UX, A/UX, SunOS, Solaris, BSD variants, and macOS among tested systems. The supplied metadata records current packaging in Homebrew, Alpine Linux, MacPorts, and Nix.

使用方式

pstree normally obtains process information from ps and displays parent-child relationships from PID 1 or selected process IDs. On Linux it can read /proc directly. Options filter branches by user, PID, or command text, limit depth, choose line-drawing characters, and request wide output.

为什么软件包爱好者会关心

This pstree is a compact example of a durable Unix utility migrating through successive distribution eras: shell script, portable C program, RCS-managed source, FTP and university-hosted releases, package-manager distribution, and finally GitHub. It remains useful because parent-child process relationships are often easier to diagnose as a tree than as a flat ps listing.

• ps supplies process data on most supported Unix systems.
• Linux /proc is read directly by the Linux implementation path.
• The similarly named pstree shipped by psmisc is a distinct implementation and should not be conflated with Fred Hucht's project.
