Support I execute and exit without echo ?

[wenerme]

$ echo "Runtime.evaluate({expression: 'window.location.toString()'})" | chrome-remote-interface inspect
>>> Runtime.evaluate({expression: 'window.location.toString()'})
>>>
{ result:
   { result:
      { type: 'string',
        value: 'http://wsjs.saic.gov.cn/txnRead01.do?y7bRbp=qmFuhMIOZ8knNLN3lIvqHXtheGH8x0lz1pV5T.U_.xN0HBZjw.5QGTKB1G89JWL.38goSDi7e_wkq27GfE17SaqAyJ2piWUpz1B5KqJoUkg1KCS9wAcmhReqzH_2t79oHUJvrKll56TvLokW' } } }
>>>

For this command I only expect

{ result:
   { result:
      { type: 'string',
        value: 'http://wsjs.saic.gov.cn/txnRead01.do?y7bRbp=qmFuhMIOZ8knNLN3lIvqHXtheGH8x0lz1pV5T.U_.xN0HBZjw.5QGTKB1G89JWL.38goSDi7e_wkq27GfE17SaqAyJ2piWUpz1B5KqJoUkg1KCS9wAcmhReqzH_2t79oHUJvrKll56TvLokW' } } }

The CLI that comes with this module is mainly for demonstration, documentation lookup and debugging purposes you shouldn't use it for scripting.

It's really easy to write an ad hoc Node.js script for what you're trying to achieve, which is basically the primary goal of this library.
