lftp

lftp is a free command-line transfer tool for Linux, suited to users who want to automate file movement and directory updates from a terminal. Its mix of protocol support, queues and recovery features makes it capable for recurring or lengthy transfers, though its platform scope and limited author support are real constraints.

Overview

Distributed under the GNU GPL, lftp brings several transfer protocols and automation tasks into one command-line program. It can retry operations after non-fatal errors, resume downloads, and keep unfinished jobs running in the background after you exit the program or close an xterm. That combination is useful when transfers take time or need to run without an open terminal session.

Version labels differ: the homepage lists 4.9.3, released on 2024-11-08, while the download page calls 4.9.2 the latest stable version. The author says current work leaves little time to support the project. Two mailing lists cover general discussion and major announcements, and development and snapshot announcements, but they do not change the stated limit on author support.

Key features

Protocols, recovery and mirroring

lftp supports FTP, HTTP, FISH, SFTP, HTTPS, FTPS and BitTorrent. This breadth can reduce the need to switch tools for different transfer types, but the command-line interface makes it a better fit for terminal users than for anyone seeking a graphical client.

Automatic retries and resumed downloads help recover from non-fatal errors and interruptions. The built-in mirror command downloads or updates a directory tree, while reverse mirror uploads or updates one on a server. These functions make lftp particularly useful for keeping local and remote directory structures in sync.

Parallel work and scheduling

lftp can transfer multiple files in parallel, and pget can use multiple connections to download one file. Queues and scheduled jobs let users organize work for later execution rather than managing each transfer separately. Together with background jobs, these features suit repeatable workflows; they are less compelling if you only need occasional, manually started transfers.

Security and downloads

FTPS and HTTPS support uses GNU TLS or OpenSSL, depending on how lftp is built. Downloads include source archives and Fedora RPM binaries, and the project also provides read-only Git access to its development source. That distribution model will suit Linux users comfortable choosing and managing software in those forms.

Pricing

Free software: free. The GNU GPL-licensed program has a free plan and no free trial. Its price makes it accessible for personal or recurring transfer work, though it does not offset the Linux-only scope or limited author support.

Platforms

lftp supports Linux. Users who need a client for Windows or macOS should choose a cross-platform alternative instead.

Who it's for

Choose lftp if you work in a Linux terminal and need protocol variety, directory mirroring, queued or scheduled work, or transfers that can resume and continue in the background. Look elsewhere if you prefer a graphical workflow, need other desktop platforms, or depend on substantial author support.

Pros and cons

Pros

• Broad protocol coverage, including FTP, SFTP, HTTPS and BitTorrent, in one command-line program.
• Retries, resumed downloads and background jobs help long-running transfers withstand interruptions and terminal closures.
• Mirroring, parallel transfers, queues and scheduling support repeatable transfer workflows.
• Free software distributed under the GNU GPL.

Cons

• Linux is the only supported platform, ruling it out for users who need Windows or macOS support.
• The author says work commitments leave little time for support.
• The homepage and download page show different version labels, which may leave users unsure which release is considered stable.
• The command-line approach is a poor fit for users who want a graphical client.

Alternatives

For a broader set of FTP and SFTP client options, browse FTP and SFTP clients or SFTP Client Software.

• WinSCP is a free, open-source Windows client supporting SFTP, FTP, FTPS, SCP, WebDAV and S3; choose it if you need Windows support or those additional protocols.
• FileZilla Client is free on Linux, macOS and Windows and supports FTP, FTPS and SFTP; choose it if you want wider platform coverage in a client.
• Cyberduck is a freemium option for macOS and Windows; consider it if you need a client for either of those platforms.
• FTP Rush is free and supports Android, iOS, Linux, macOS and Windows; choose it if mobile or broader desktop platform support matters.
• gFTP is a free Linux file transfer client and is another option for Linux users.
• CrossFTP is a freemium client for Linux, macOS and Windows, with a free plan and a trial; consider it if you need cross-platform support.
• NcFTP is a free client for Linux, macOS and Windows; choose it if you need a client across those platforms.
• Faro is a free, open-source option for Linux, macOS and Windows; consider it if you want a cross-platform alternative.

Verdict

lftp is a strong fit for Linux terminal users who need reliable, repeatable transfers across varied protocols, especially when mirroring or scheduling jobs. Its free GNU GPL distribution is appealing, but users who need a graphical workflow, broader platform support or more available author support should choose another client.
