title: Run SCP From Command Line With Password
body: <p>I need way to run SCP from the command line with a password.</p>
  
  <p>Specifically, it's because I need to use the Python library Fabric to have one remote machine SCP to another remote machine, without the file passing through the local machine (it's a large file, and the two remote machines have a much quicker connection between each other than my local machine has with either of them.) The two remote machines are running CentOS.</p>
  
  <p>But none of those details are particularly important with respect to the main question.</p>
