CLI EXAMPLES

$ uberlev

Get the first 10 keys in the database, the path is optional but if ommited a database will be created in the current working directory.

$ uberlev path/to/db --keys --limit 10

or short hand

$ uberlev path/to/db -kl 10

Get the first ten records starting at bazz and ending at zomg.

$ uberlev path/to/db --limit 10 --start 'bazz' --end 'zomg'

Get the key welcome from inside the 2 sublevels deep

uberlev ./db --cd greetings/en --get 'welcome'

For connecting to a multilevel enabled instance, specify the port parameter:

uberlev --port 1337 --keys ...

REPL

Start the REPL by providing only a path or host and port

$uberlev path/to/db

Commands in the REPL also match the API. But wait! There are a subset of commands that make common operations faster, easier and more fun. The following keys and sublevels are arbitrary and for the purpose of this example only.

ls A listing of keys in the current sublevel

Supports tab completion, same as the javascript function.

>ls

cd create or change into a sublevel
