sync-exec

sync-exec

An fs.execSync replacement until you get it natively from node 0.12+

Advantages

Inspired by exec-sync but comes with a few advantages:

• no libc requirement (no node-gyp compilation)
• no external dependencies
• returns the exit status code
• you can pass exec options
• multiple commands should work pretty safely

Installation

[sudo] npm install sync-exec

Signiture

exec(cmd[, timeout][, options]);

Examples

var exec = require('sync-exec');

// { stdout: '1\n',
//   stderr: '',
//   status: 0 }
console.log(exec('echo 1'));

// You can even pass options, just like for [child_process.exec](http://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback)
console.log(exec('ls -la', {cwd: '/etc'}));

// Times out after 1 second, throws an error
exec('sleep 3; echo 1', 1000);

How it works (if you care)

Your commands STDOUT and STDERR outputs will be channeled to files, also the exit code will be saved. Synchronous file readers will start listening to these files right after. Once outputting is done, values get picked up, tmp files get deleted and values are returned to your code.
