title: How to check if scp command is available?
body: <p>I am looking for a multiplatform solution that would allow me to check if <code>scp</code> command is available.</p>
  
  <p>The problem is that scp does not have a <code>--version</code> command line and when called without parameters it will return with exit code <code>1</code> (error).</p>
  
  <p>Update: in case it wasn't clear, by multiplatform I mean a solution that will work on Windows, OS X and Linux without requiring me to install anything.</p>
