title: Is there a way to "refresh" the terminal/iTerm without closing the current sessions?
body: <p>I just updated my xcode command line tool in my iTerm2 and it seems like I need to restart my iTerm to put that to work, since when I try to use</p>
  
  <pre><code>tns build ios
  </code></pre>
  
  <p>command to build my nativescript project for iOS, it always echos back</p>
  
  <pre><code>xcodebuild execution failed. Make sure that you have latest Xcode and tools installed.
  </code></pre>
  
  <p>which shouldn't be true.
  However, I am having a session that's currently running to upload a huge file to my cloud drive which has spent 7 hours to have uploaded 37%, and it doesn't support resume uploading from a break-point.</p>
  
  <p>So, is there any way to refresh the terminal without closing the active session?</p>
  
  <p>Thanks guys</p>
