title: Call multiple commands from powershell e.g psftp
body: <p>I am trying to SFTP a file from powershell using psftp.exe (putty). I can run single command such as open but I need to change the default directory and then put the file. The following code takes me to psftp but ignores lines from cd .. to bye. I guess I can run a batch file which has the sftp commands but if possible I want to accomplish using powershell.</p>
  
  <pre><code>$file = "C:\Source\asdf.csv"
  $user = "user"
  $pass = "pass"
  $hst = "host"
  $path="C:\ProgramFiles\psftp.exe"
  $cmd = @"
  -pw $pass $user@$hst
  cd ..
  cd upload
  put $file
  bye
  "@
  
  invoke-expression "$path $cmd"
  </code></pre>
