title: how to use SCP or SFTP in the script file for file transfer
body: <p>This script file reads the hello_world.py and source$n.vtu will be the input
  data. In the end I will produce some .png files. I would like to transfer them to my local computer from the remote machine (cluster or super computer).
  Can anyone tell me how to do with SCP or SFTP. Thanks!</p>
  
  <pre><code>low=0
  high=9
  mult=2
  for i in $(eval echo {$low..$((high/mult))}); do
      n=$(printf '%06d' $((i*mult)))
     ./pvpython hello_world.py source$n.vtu
  done
