npm install exit-error

Usage

var spawn = require('child_process').spawn
var ExitError = require('exit-error')

function rm(path, next) {
  var rm_ = spawn('rm', ['-rf', path])
  rm_.on('error', next)
  rm_.on('exit', function (code, signal) {
    next(ExitError('rm', code, signal))
  })
}

rm('foo', function (err) {
  if (err) throw err
})
