lftp is a command-line program client for several file transfer protocols. lftp is designed for Unix and Unix-like operating systems. It was developed by Alexander Lukyanov, and is distributed under the GNU General Public License.
lftp can transfer files via FTP, FTPS, HTTP, HTTPS, FISH, SFTP, BitTorrent, and FTP over HTTP proxy. It also supports the File eXchange Protocol (FXP), which allows the client to transfer files from one remote FTP server to another.
Among lftp's features are transfer queues, segmented file transfer, resuming partial downloads, bandwidth throttling, and recursive copying of file directories. The client can be used interactively or automated with scripts. It has Unix shell-like job control, and a facility for scheduling file transfers for execution at a later time.
