child_process.exec()genera un shell y ejecuta un comando dentro de ese shell, pasando elstdouty elstderral callback cuando se completa. Internamente utilizabufferDocchild_process.execSync()una versión síncrona y bloqueante dechild_process.exec()Docchild_process.execFile()similar achild_process.exec(), excepto que genera el comando directamente sin generar primero un shell de forma predeterminada Docchild_process.execFileSync()una versión síncrona y bloqueante dechild_process.execFile()Docchild_process.spawn()genera un shell y ejecuta un comando devolviendo unstreamy que debemos gestionar por eventos Docchild_process.spawnSync()una versión síncrona y bloqueante dechild_process.spawn()Docchild_process.fork()Es similar achild_process.spawn()solo que nos permite enviar mensajes al proceso hijo Doc
