RPM Package Repository

To add the duck repository to your system you need to put a file duck.repo with following content into /etc/yum.repos.d/.

Snapshot Builds

Copy and paste 

echo -e "[duck-nightly]\n\
name=duck-nightly\n\
baseurl=https://repo.cyberduck.io/nightly/\$basearch/\n\
enabled=1\n\
gpgcheck=0" | sudo tee /etc/yum.repos.d/duck-snapshot.repo > /dev/null

to add the configuration.

echo -e "[duck-stable]\n\
name=duck-stable\n\
baseurl=https://repo.cyberduck.io/stable/\$basearch/\n\
enabled=1\n\
gpgcheck=0" | sudo tee /etc/yum.repos.d/duck-stable.repo > /dev/null

To install Cyberduck CLI use 

sudo yum install duck

DEB Package Repository

Add the duck repositories to your /etc/apt/sources.list manually: 

deb https://s3.amazonaws.com/repo.deb.cyberduck.io nightly main
deb https://s3.amazonaws.com/repo.deb.cyberduck.io stable main

or using 

echo -e "deb https://s3.amazonaws.com/repo.deb.cyberduck.io stable main" | sudo tee /etc/apt/sources.list.d/cyberduck.list > /dev/null

You need to download the GPG public key from keyserver.ubuntu.com to verify the integrity of the packages: 

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys FE7097963FEFBE72

Synchronize the repository using 

sudo apt-get update

To install or upgrade Cyberduck CLI use 

sudo apt-get install duck

Note: You may get a conflict with another package named duck. As a workaround, install with a specific version number like sudo apt-get install duck=6.7.1.28683.

Arch Linux Package

Manual installation

Packages can also be found for ​download.

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").

Protocol Fully Qualified URI required Absolute Path Relative Path
Windows Azure Storage No azure:/<container>/<key> azure:<container>/<key>
Backblaze B2 Cloud Storage No b2:/<container>/<key> b2:<container>/<key>
WebDAV (HTTP) Yes (dav://<hostname>/<path>)
WebDAV (HTTPS) Yes (davs://<hostname>/<path>)
Dracoon (Email Address) Yes (dracoon://<hostname>/<path>)
Dropbox No dropbox:/<path> dropbox:<path>
Local No file:/<path> file:<path>
FTP (File Transfer Protocol) Yes (ftp://<hostname>/<path>)
FTPS (Explicit Auth TLS) Yes (ftps://<hostname>/<path>)
Google Drive No googledrive:/<path> googledrive:<path>
Google Cloud Storage No gs:/<path> gs:<path>
Microsoft OneDrive No onedrive:/<path> onedrive:<path>
Amazon S3 s3://<hostname>/<container>/<key> s3:/<container>/<key> (using s3.amazonaws.com) s3:<container>/<key> (using s3.amazonaws.com)
SFTP (SSH File Transfer Protocol) Yes (sftp://<hostname>/<path>)
Spectra S3 (HTTPS) Yes (spectra://<hostname>/<container>/<key>)
Rackspace Cloud Files (US) No rackspace:/<container>/<key> rackspace:<container>/<key>
Swift (OpenStack Object Storage) Yes (swift://<hostname>/<container>/<key>)

Examples

  • List all buckets in S3 with 
    duck --username <Access Key ID> --list s3:/
  • List all objects in a S3 bucket with 
    duck --username <Access Key ID>  --list s3:/<bucketname>/

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.

Use --vault <path> in conjunction with --upload to unlock a vault. This allows to upload into a sub directory of a vault where the auto-detect feature does otherwise not work.

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/
