# Command: console
|
|
|
|
The `terraform console` command provides an interactive console for
|
|
evaluating [expressions](/docs/language/expressions/index.html).
|
|
|
|
## Usage
|
|
|
|
Usage: `terraform console [options]`
|
|
|
|
This command provides an interactive command-line console for evaluating and
|
|
experimenting with [expressions](/docs/language/expressions/index.html).
|
|
This is useful for testing interpolations before using them in configurations,
|
|
and for interacting with any values currently saved in
|
|
[state](/docs/language/state/index.html).
|
|
|
|
If the current state is empty or has not yet been created, the console can be
|
|
used to experiment with the expression syntax and
|
|
[built-in functions](/docs/language/functions/index.html).
|
|
|
|
You can close the console with the `exit` command or by pressing Control-C
|
|
or Control-D.
|
|
|
|
For configurations using
|
|
[the `local` backend](/docs/language/settings/backends/local.html) only,
|
|
`terraform console` accepts the legacy command line option
|
|
[`-state`](/docs/language/settings/backends/local.html#command-line-arguments).
|
|
|
|
## Scripting
|
|
|
|
The `terraform console` command can be used in non-interactive scripts
|
|
by piping newline-separated commands to it. Only the output from the
|
|
final command is printed unless an error occurs earlier.
|
|
|
|
For example:
|
|
|
|
```shell
|
|
$ echo "1 + 5" | terraform console
|
|
6
|
|
```
|
|
|
|
## Remote State
|
|
|
|
If [remote state](/docs/language/state/remote.html) is used by the current backend,
|
|
Terraform will read the state for the current workspace from the backend
|
|
before evaluating any expressions.
