The stdout and stderr arguments passed to the callback will contain the stdout and stderr output of the child process. nodejs docs needs to give at least one example as it only states: stdio | Child's stdio configuration. Thanks for the prompt follow-up and action on this issue. A Writable Stream to stdin. In "old" streams mode the stdin stream is paused by default, so one must call process.stdin.resume() to read from it. I know this is a very old question but I didn’t see anybody talking about the main difference between process.stdout.write and console.log and I just want to mention it..

The process object is an instance of EventEmitter and emits the following events − ... stdout. This package improves child_process methods with:. Process execution for humans. A Writable Stream to stdout. stderr. ; Supports shebang binaries cross-platform. Checklist make -j8 test (UNIX), or vcbuild test nosign (Windows) passes tests and/or benchmarks are included documentation is changed or added commit message follows commit guidelines Affected core subsystem(s) process, console Description of change This is a step in making console safe, swallows EPIPE and other errors by registering an empty 'error' event listener. 2: stderr.
