### Event: 'close'

This event is emitted when the stdio streams of a child process have all

terminated.  This is distinct from 'exit', since multiple processes

might share the same stdio streams.

    var spawn = require('child_process').spawn,

        grep  = spawn('grep', ['ssh']);

      console.log('child process terminated due to receipt of signal '+signal);

    });

      console.log('stderr: ' + data);

    });

      console.log('child process exited with code ' + code);

    });

      console.log('ps stderr: ' + data);

    });

      if (code !== 0) {

        console.log('ps process exited with code ' + code);

      }

      console.log('grep stderr: ' + data);

    });

      if (code !== 0) {

        console.log('grep process exited with code ' + code);

      }
