Cross platform children list of a PID

Package Exports

  • pidtree

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (pidtree) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

🚸 Cross platform children list of a PID.
Coded with ❤️ by Simone Primarosa.

Motivation

The only package that does this simple but tricky job is ps-tree but the project is unmaintained and furthermore the logic is wrong.

Usage

var pidtree = require('pidtree')

// Get childs of current process
pidtree(process.pid, function (err, stat) {
  console.log(stat)
  // => []
})

// Include the given pid in the result array
pidtree(process.pid, {root: true}, function (err, stat) {
  console.log(stat)
  // => [727]
})

// Get all the processes of the System on *nix
pidtree(1, function (err, stat) {
  console.log(stat)
  // => [41,45,43,530,47,50, ..., 41241, 32]
})
