cbt CLI overview

The cbt CLI is a command-line interface for performing several different operations on Bigtable. It is written in Go using the Go client library for Bigtable. Source code for the cbt CLI is available in the GoogleCloudPlatform/google-cloud-go GitHub repository. This repository is a mirror of code.googlesource.com/gocloud.

For information about Bigtable in general, see the overview of Bigtable.

Install the `cbt` CLI

You can install the cbt CLI as a gcloud CLI component.

The cbt CLI does not implement smart retries or error handling. When working in production environment, use a Bigtable client library or the Google Cloud console.

Install the gcloud CLI.
Run the following commands:
```
gcloud components update
gcloud components install cbt
```
If the cbt CLI is already installed, the terminal window displays the All components are up to date message.

Verify the installation

Run the following cbt CLI command to verify installation of the CLI:

cbt listinstances

The terminal window displays two columns named Instance Name and Info.

Create a .cbtrc file

You can store required options and parameters, such as -project, -instance, -creds, -admin-endpoint, or -data-endpoint options, in a single .cbtrc file for convenience.

In your .cbtrc file, configure cbt to use your project and instance by replacing project-id with the ID for the project where you created your Bigtable instance:
```
echo project = project-id > ~/.cbtrc
echo instance = quickstart-instance >> ~/.cbtrc
```
Verify that you set up the .cbtrc file correctly:
```
cat ~/.cbtrc
```
The terminal displays the contents of the .cbtrc file, which looks similar to the following settings:
```
project = project-id
instance = quickstart-instance
```
Now you can use the cbt CLI with your instance.
