Command-line Interface¶

The Determined command-line interface (CLI) is installed under the name det. Most uses of it require arguments specifying a type of object to act on and the action to perform, followed by any additional arguments or options. For example,

det experiment config 17

displays the configuration for experiment 17. Some commands have an additional level of nesting:

det experiment label add 17 foobar

adds the label “foobar” to experiment 17.

The names of some objects, actions, and options may be abbreviated; alternative names are shown in the full reference in parentheses. For example, these two commands are equivalent:

det -u admin experiment list
det --user admin experiment list

as are these two:

det e config 17
det experiment config 17

Additionally, when list is a valid action, it is the default when no action is specified, so the following pairs of commands are also equivalent:

det e
det experiment list

det s
det slot list

Providing -h or --help as an argument anywhere will cause the CLI to exit after printing help text for the object or action specified up to that point.
