🚸 Cross platform children list of a PID.

Coded with ❤️ by <a href="#authors">Simone Primarosa</a>.

Synopsis

This package is really similar to ps-tree but is faster, safer and provides sub-children results.
Furthermore ps-tree is unmaintained.

Uuh, and a fancy CLI is also available!

Usage

var pidtree = require('pidtree')

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

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

// Get all the processes of the System (-1 is a special value of this package)
pidtree(-1, function (err, pids) {
  console.log(pids)
  // => [530, 42, ..., 41241]
})

// Include PPID in the results
pidtree(1, {advanced: true}, function (err, pids) {
  console.log(pids)
  // => [{ppid: 1, pid: 530}, {ppid: 1, pid: 42}, ..., {ppid: 1, pid: 41241}]
})

// If no callback is given it returns a promise instead
const pids = await pidtree(1)
console.log(pids)
// => [141, 42, ..., 15242]

Please if your platform is not supported file an issue.

CLI

Show a tree of the processes inside your system inside your terminal.

npx pidtree $PPID

Just replace $PPID with one of the pids inside your system.

Or don't pass anything if you want all the pids inside your system.

npx pidtree

To display the output as a list, similar to the one produced from pgrep -P $PID, pass the --list flag.

npx pidtree --list

API

pidtree(pid, [options], [callback]) ⇒ [Promise.<Array.<Object>>]

Get the list of children pids of the given pid.

Kind: global function
Returns: Promise.<Array.<Object>> - Only when the callback is not provided.
Access: public

Param	Type	Default	Description
pid	Number | String		A pid. If -1 will return all the pids.
[options]	Object		Optional options object.
[options.root]	Boolean	false	Include the provided pid in the list. Ignored if -1 is passed as pid.
[callback]	function		Called when the list is ready. If not provided a promise is returned instead.
