To view a list of commands in the DQO Shell run the following command

dqo> help

You can also check the description of every command by adding --help (or -h) parameter to the name of the command.


DQO Shell supports autocompletion, so you only need to start typing the command, hit the Tab and the DQO Shell will show you a list available options.

For example, if you want to add a new connection using the connection add command, just start typing c. The suggested command will be displayed below, and you can select the connection using the Tab key.


DQO also supports autocomplete of parameters, connection names or table names.

For example, if you want to run all enabled checks on single table, simply start typing - or -- after the check run command, and the available parameters will be displayed. Just start typing the name of the parameter and hit the Tab key to use autocomplete.


Add the connection name using the --connection= parameter and select the connection using the Tab key. Then you can narrow down your choice to a single table with --table= parameter.


Starting DQO in server mode

You can run DQO in a server mode that will continuously run the programme.

To do this, simply enter the command below in your terminal

$ dqo run
To terminate dqo running in the background, simply use the Ctrl+C.

For more information on the run command, please refer to the Command-line interface section.

Using DQO commands on the command-line interface

You can also use any DQO commands directly on the command line. Just add dqo before the name of the command. For example, to run all the enabled checks use the following command

$ dqo check run
