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
