URI
The <url> argument for --copy, --download, --upload and --synchronize must be fully qualified URIs with protocol, hostname and absolute remote path such as ftp://<hostname>/<folder>/<file> for a file or ftp://<hostname>/<folder>/ for a directory. For cloud storage providers, reference the target container (aka bucket) name in the URI like s3://bucketname/key.
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.
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
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
