go-ps is a library for Go that implements OS-specific APIs to list and manipulate processes in a platform-safe way. The library can find and list processes on Linux, Mac OS X, and Windows.

If you're new to Go, this library has a good amount of advanced Go educational value as well. It uses some advanced features of Go: build tags, accessing DLL methods for Windows, cgo for Darwin, etc.

How it works:

• Darwin uses the sysctl syscall to retrieve the process table, via cgo.
• Unix uses the procfs at /proc to inspect the process tree.
• Windows uses the Windows API, and methods such as CreateToolhelp32Snapshot to get a point-in-time snapshot of the process table.

Install using standard go get:

$ go get github.com/mitchellh/go-ps
...

Want to contribute? Here is a short TODO list of things that aren't implemented for this library that would be nice:

• FreeBSD support
• Plan9 support
• Eliminate the need for cgo with Darwin
