Usage
Usage:duck [options...]
Run --help to get the option screen.
URLs in arguments must be fully qualified. Paths can either denote a remote file (ftps://user@example.net/resource) or folder (ftps://user@example.net/directory/) with a trailing slash. You can reference files relative to your home directory with /~ (ftps://user@example.net/~/).
Connection Profiles
You can install additional connection profiles in the application support directory. Use the --profile option to reference a connection profile file to use not installed in the standard location.
URI
The <url> argument for --copy, --download, --upload and --synchronize must satisfy following rules:
- Each URL must start with a scheme and a colon (https:) (unless you specify a --profile)
- Depending on the type of protocol you are referencing different rules apply
- For all protocols where no default hostname is set (e.g. WebDAV, SFTP, and FTPS) you must use a fully qualified URI https://user@hostname/path
- For all protocols where a default hostname is set, but you are allowed to change it (e.g. S3) you may use fully qualified URIs or
Absolute paths: s3:/bucket/path
Relative paths: s3:user@path or s3:user@/path. Omiting the first slash in a relative path uses the default home directory for this protocol. - For all protocols where a default hostname is set and you are not allowed to change it (e.g. OneDrive, Dropbox, Google Drive) you may use any combination of the above with the following rules:
Fully Qualified URIs are parsed as relative paths. onedrive://Some/Folder/ is parsed as onedrive:Some/Folder.
- For all protocols where a default path is set and you are not allowed to change it (e.g. accessing a prebuilt NextCloud profile with a path set to /remote.php/webdav). You are allowed to change the path but it will be appended to the default path. Making nextcloud:/path really nextcloud:/remote.php/webdav/path.
Spaces and other special-characters are not required to be percent-encoded (e.g. %20 for space) as long as the path is quoted duck --upload "scheme://hostname/path with/spaces" "/Path/To/Local/File With/Spaces").

Generic options
--retry
Retry requests with I/O failures once per default. Useful on connection timeout or latency issues.
--verbose
Print protocol transcript for requests and responses. This includes the HTTP headers.
--nokeychain
Do not save passwords in login keychain (macOS), credentials manager (Windows) or plain text password file (Linux).
--quiet
Suppress progress messages.
--throttle
Throttle bandwidth to the number of bytes per second.
Credentials
You can pass username as part of the URI prepending to the hostname with username@host. Alternatively use the --username option. You can give the password with the --password option or you will be prompted before the connection is opened by the program if no password matching the host is found in your login keychain (OS X) or user configuration shared with Cyberduck (Windows).
Private Key
When connecting with SFTP you can give a file path to a private key with --identity for use with public key authentication.
Tenant Name
When connecting with OpenStack Swift you can set the tenant name (OpenStack Identity Service, Keystone 2.0) or project (OpenStack Identity Service, Keystone 3.0) with --username <tenant>:<user>.
Downloads with --download
Glob pattern support for selecting files to transfer
You can transfer multiple files with a single command using a glob pattern for filename inclusion such as duck --download ftps://<hostname>/directory/*.css .
Uploads with --upload
Glob pattern support for selecting files to transfer
If your shell supports glob expansion you can use a wildcard pattern to select files for upload like duck --upload ftps://<hostname>/directory/ ~/*.jpg.
Use of ~
You can use the tilde to abbreviate the remote path pointing to the remote home folder as in sftp://duck.sh/~/. It will be expanded when constructing absolute paths.
Remote directory listings with --list
Make sure to include a trailing '/' in the path argument to denote a directory. Use the -L option to print permission mask and modification date in addition to filename.
Edit with --edit
You can edit remote files with your preferred editor on your local system using the --edit command. Use the optional --application option to specify the absolute path to the external editor you want to use.
Multiple transfer connections with --parallel
Transfer files with multiple concurrent connections to a server.
Cryptomator
Access to your Cryptomator vaults from the command line. When accessing a vault using --download, --list or --upload, you will be prompted to provide the passphrase for the vault if not found in the keychain.
Samples
Watching changes in directory with fswatch and upload
fswatch is a file change monitor; an application to watch for file system changes. Refer to their documentation.
fswatch -0 ~/Sites/mywebsite/ | xargs -0 -I {} -t sh -c 'f="{}"; duck --upload ftps://<hostname>/sandbox`basename "${f}"` "${f}" -existing overwrite'
Upload build artifacts from continuous integration (Jenkins) to CDN
Use a post build script action.
cd ${WORKSPACE}; find build -name '*.tar' -print0 | xargs -0 -I {} -t sh -c 'f="{}"; duck --quiet --retry --existing skip --region DFW --upload rackspace://<container>/ "${f}"'
Upload files matching glob pattern to Windows Azure
duck --username kahy9boj3eix --upload azure://kahy9boj3eix.blob.core.windows.net/<containername>/ *.zip
Download files matching glob pattern from FTP
duck -v --download ftp://mirror.switch.ch/mirror/apache/dist/httpd/*.gz ~/Downloads
Download file from Amazon S3 public bucket
duck --verbose --download s3://repo.maven.cyberduck.io/releases/ch/cyberduck/s3/6.1.0/s3-6.1.0.jar ~/Downloads/
