title: Logging location of lftp
body: <p>While using lftp, it will log the file transfer to the ~/.lftp/transfer_log when xfer:log setting is set to "yes".</p>
  
  <p>What will happen when there are two instances of lftp running at the same time? Will the log file be mixed up?</p>
  
  <p>Is there a way to change where the log file will be write to?</p>
  
  <p>Thanks.</p>
