spawnx

Remover

Flexible spawn() with exec() syntax.

Install

npm install spawnx

API

spawnx(command, [options,] callback);

Usage

var run = require('spawnx');
 
run('/path/to/command --foo bar 1', function(err, stdout, stderr) {
  console.log(err || stdout);
})
 
// let's pipe the output from the command to a log file as it comes.
var stream = fs.createWriteStream('output.log');
 
run('another_command --test', { cwd: '/tmp', stdout: stream }, function(err) {
  console.log('Finished');
  stream.close();
})

Options

Whatever options you pass in the options argument will be passed to the actual spawn() call. There are two additional options that you may pass: stdout and stderr. If present, spawnx will pipe the output from the spawn command to those streams. That way you can have live output of a running command.

Also important: the path to command may be relative, in which case the full path is looked for by searching the environment's $PATH. If now options.cwd is set, the command's dirname is set as the cwd for the spawn call.
