Quick Start

Datui is used to visualize tabular data in the terminal.

See the Installation Manual for help installing Datui.

Opening a File

To open a file, simply provide it as an argument.

datui /path/to/file.csv

Datui will load your data into a full screen terminal display.

See the Loading Data section for details about supported file formats and options.

Navigating

You may scroll through your data using the arrow keys, or familiar vim keybindings (j/k for up/down, h/l for left/right).

You may also jump pages with the Page Up and Page Down keys.

Getting Help

See command line arguments:

datui --help

Activate the built-in help display at any time by pressing ? or F1 (F1 works in text fields too, e.g. query input). Press Esc or ? to close it.

Understanding the UI

• The main Datui view window shows your data in full screen, with a header row at the top and a toolbar across the bottom of the screen.
• The toolbar at the bottom contains a quick reference for the keystrokes to activate the various features of Datui.
• Certain features will open pop-over menus, or change the full screen view. Press Esc to go back to the prior page.

More Examples

Open a hive-partitioned directory:

datui --hive /path/to/directory

Note: The directory should contain files all of the same type

Or, a glob pattern to hive-partitioned parquet:

datui --hive "/path/to/directory/**/*.parquet"

Note: It is usually necessary to quote the glob pattern to prevent shell expansion.

Now that you understand the basics, learn about the rest of Datui’s features by reading the User Guide.
