'''lftp''' is a [[Command-line interface|command-line]] program [[Client (computing)|client]] for several [[file transfer]] [[Communication protocol|protocols]]. lftp is designed for [[Unix]] and [[Unix-like]] [[operating system]]s. It is developed by Alexander Lukyanov, and is distributed under the [[GNU General Public License]].

lftp can transfer files via [[File Transfer Protocol|FTP]], [[FTPS]], [[HTTP]], [[HTTPS]], [[Files transferred over shell protocol|FISH]], [[SSH file transfer protocol|SFTP]], [[BitTorrent (protocol)|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 [[Directory (computing)|file directories]]. The client can be used interactively or automated with scripts. It has [[Unix shell]]-like [[Job control (Unix)|job control]], and a facility for scheduling file transfers for execution at a later time.

==Development history==
lftp was initially developed as part of the ftpclass package.<ref>https://groups.google.com/forum/#!topic/relcom.tcpip/uhvSllkqQHo relcom.tcpip August 1, 1996</ref> Subsequently it grew and became a more capable program (e.g., mirroring capability was added), and was renamed to lftp in February 1997.<ref>{{cite web
 | title = Old lftp change log
 | url   = https://lftp.yar.ru/NEWS}}</ref> 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.
