exec

exec

Call a child process with the ease of exec and safety of spawn

Why?

This module provides the best of both worlds of spawn and exec

It will callback with 2 strings containing stdout and stderr (like child_process.exec), but will take an array of process arguments (like child_process.spawn) to avoid any potentially harmful shell expansion.

Usage

var exec = require('exec');

Example

var exec = require('exec');

exec(['ls', '-lha'], function(err, out, code) {
  if (err) throw err;
  process.stdout.write(out);
  process.exit(code);
});

The example above will call ls -lha safely, by passing the arguments directly to exec(2) without using an shell expansion/word splitting.

It returns a child_process.spawn object, and callbacks with any stdout, stderr, and the exit status of the command. The above example will throw an error if any stderr was produced, otherwise it will print the stdout and exit with the exit code of ls.

Functions

exec(['args'], [opts], callback)

opts is additional options to pass to child_process.spawn

Installation

npm install exec
