How do I add export CLI='docker run -it --entrypoint cardano-cli -e NETWORK=testnet ...' so I can run CLI on Mac OS Monterey zshrc

If you're a macOS Monterey user looking to simplify your workflow with Cardano's command-line interface (CLI), you might want to create an alias for the Docker command. This way, you can run the command easily without typing it out each time. In this article, we will guide you through adding the following export command to your .zshrc file:

export CLI='docker run -it --entrypoint cardano-cli -e NETWORK=testnet ...'

Understanding the Command

The command above is a way to set an environment variable named CLI, which contains a command that launches the Cardano CLI within a Docker container configured for the testnet. The ellipsis (...) indicates that there may be additional options or parameters that you would include depending on your specific needs.

Why Use the CLI Alias?

Using an alias like this has several benefits:

  • Efficiency: You won't need to type the entire Docker command every time you want to use Cardano's CLI.
  • Convenience: Easily switch environments or add more options by modifying just one line in your .zshrc file.
  • Portability: By exporting the command, it becomes available in all terminal sessions.

Steps to Add the Command to Your .zshrc

  1. Open the Terminal: You can find the Terminal application in your Applications > Utilities folder, or you can use Spotlight by pressing Command + Space and typing "Terminal."

  2. Edit the .zshrc File: Use a text editor to open your .zshrc file. You can use the built-in nano editor by executing:

    nano ~/.zshrc

  3. Add the Export Command: Scroll to the bottom of the .zshrc file and add the export command:

    export CLI='docker run -it --entrypoint cardano-cli -e NETWORK=testnet ...'

  4. Save Your Changes: If you're using nano, press CTRL + O to save the file, then CTRL + X to exit the editor.

  5. Reload Your Terminal Configuration: Run the following command to apply your changes:

    source ~/.zshrc

  6. Test the Command: You can now test if the alias works by typing:

    $CLI

    This should launch the Cardano CLI in a Docker container.

Additional Explanation and Examples

If you need to customize the command further, such as specifying different networks or settings, you can easily modify the CLI variable in your .zshrc file. For example, if you want to work with the mainnet instead of the testnet, you could modify it as follows:

export CLI='docker run -it --entrypoint cardano-cli -e NETWORK=mainnet ...'

Practical Example

To demonstrate how this could enhance your workflow, consider a scenario where you're frequently checking the status of the Cardano network. Instead of entering the full Docker command every time, simply type $CLI query tip to get the latest block information efficiently.

Conclusion

Creating an alias for the Cardano CLI in your macOS Monterey terminal is a straightforward way to streamline your workflow. By following the steps above, you'll save time and reduce the chances of errors when running the Cardano CLI commands.
