Sometimes you have to copy whole directories recursively to an FTP-server. Many FTP servers are not able to handle bulk uploads directly. Here lftp comes to the rescue. lftp allows to upload or download entire directories irrespective of the capabilities of the FTP server. Assume we want to upload…
