is available). There’s also autocomplete for most commands and their
parameters.Individual files can be copied between the local filesystem and
ZooKeeper. Recursively copying from the filesystem to ZooKeeper is
supported as well, but not the other way around since znodes can have
content and children.(CONNECTED) /> cp file:///etc/passwd zk://localhost:2181/passwd
