What is "lftp"

lftp is a command-line file transfer program ( FTP client) for UNIX and Unix-like systems. It was written by Alexander Lukyanov and is made available under the GNU General Public License. __NOTOC__ Besides FTP, it also supports FTPS, HTTP, HTTPS, HFTP, FISH, and SFTP. The program also supports FXP, allowing for data transfers between two FTP servers bypassing the client machine. A simple BitTorrent client is also included via the torrent command.

In addition to features common in advanced FTP clients, such as recursively mirroring entire directory trees and resuming downloads, lftp also supports more advanced functionality. Transfers can be scheduled for execution at a later time, bandwidth can be throttled, transfer queues can be created, and Unix shell-like job control is supported. The client can be used interactively or automated with scripts.

It also has an option called segmented file transfer that allows more than one connection for the same file, bypassing a maximum download speed per file when some servers establish a maximum speed per connection.
