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.
Lftp was initially developed as part of the ftpclass package (announced August 1, 1996 in relcom.tcpip). Subsequently it grew and become a more capable program (e.g., mirroring capability was added), and therefore the package was renamed to lftp in February 1997. The initial goals of development were robustness, automatic resuming of transfers, and increasing transfer speed by transferring parts of a file in parallel using several connections as well as by protocol pipelining. Version 2.0 introduced HTTP and IPv6 support in 1999, more protocols were added later.
