    sync-exec

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

    Upgrading to 0.12.x is usually safe. At that point it will use child_process.execSync.

    You can still force the emulated version passing {forceEmulated: true} to the options argument.

    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 execSync options
    • multiple commands should work pretty safely

    Installation

    [sudo] npm install sync-exec
    

    Signature

    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.
