overview
Command-line interface for Cyberduck (a multi-protocol file transfer tool)
history
duck is the command-line interface for Cyberduck, the long-running file-transfer client. It gives Cyberduck's multi-protocol transfer stack a scriptable shell front end for FTP, SFTP, WebDAV, S3-compatible storage, OpenStack Swift, and other cloud-storage backends.
Cyberduck began as a macOS file-transfer application and its official changelog reaches back to early 2000s releases. The current source repository describes Cyberduck as a libre file transfer client for macOS and Windows, with a command-line interface for Linux, macOS, and Windows.
The duck CLI packages the Cyberduck transfer engine for terminal users. Its homepage presents it as Cyberduck for the command line and documents Homebrew, Chocolatey, RPM, and DEB installation paths.
duck's adoption follows Cyberduck's protocol breadth rather than the popularity curve of a standalone Unix transfer tool. Users choose it when they want one command-line client that speaks the same storage profiles and cloud protocols as Cyberduck and Mountain Duck.
Packaging through Homebrew, Chocolatey, Debian/Ubuntu-style repositories, and RPM repositories made the CLI available to automation users who do not run the desktop application.
The CLI is used for uploads, downloads, remote editing workflows, and copies between servers or cloud providers. It is especially relevant for scripted access to storage backends that otherwise require provider-specific CLIs.
Because the same upstream project also ships GUI Cyberduck and Mountain Duck components, duck sits at the command-line edge of a broader file-transfer product family.
duck is interesting because the package name is short and generic while the project identity is really Cyberduck CLI. Package databases should preserve that relationship so users do not confuse it with unrelated projects named duck.
It also demonstrates a common packaging pattern: a GUI application exposes a CLI package with a different formula name, while sharing source code and protocol implementations with the main application.
security posture
narrow executable package without higher-risk signals.
green risk · low confidence · appliance
Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
