subcomandante

node-subcomandante

Morir fue lo unico que el subcomandante hizo sin su comandante.

This module is a companion to comandante. It is meant to solve the problem of child processes which must die along with their parents in node, which often leaves children hanging.

Usage

subcomandante works just like comandante:

// comandante
var run = require('comandante')
run(['tail', '-f', '/dev/null']) // will wait forever.
process.exit(0)
 
// subcomandante
var run = require('subcomandante')
run(['tail', '-f', '/dev/null']) // will exit with parent.
process.exit(0)

opts.waitPid

Pass in a pid with opts.waitPid to wait on that process, instead of the current process (process.pid).

run(['nc', '-l', '1234'], {waitPid: 1919})

subcom binary

> subcom
usage: subcom <pid> <cmd>...
run <cmd> until <pid> exits.

The subcom binary is very simple-- it runs a child process until process with given <pid> exits. It forwards all io, and exits with the same error code as the child. It will also employ brute strength (kill -9) if the child refuses to exit gracefully.
