The command "goimports ${filename}.go" is used to automatically format and organize the imports in a Go programming language file.

In Go, import statements are used to bring in external packages into the code. These packages provide various functionalities that can be utilized in the program. The "goimports" command helps ensure that all the required packages are imported correctly and that the import statements are organized in a specific order.

Here's how the command works:

1. The "${filename}.go" part is a placeholder that should be replaced with the actual name of the file you want to format. For example, if your file is named "example.go", you would replace "${filename}.go" with "example.go".

2. Once you have the correct filename, you can run the command. The "goimports" tool will analyze the file and automatically add or remove any necessary import statements based on the packages that are being used in the code.

3. Additionally, it will sort the import statements alphabetically and group them based on whether they are the standard library packages, third-party packages, or local packages.

By running the "goimports ${filename}.go" command, you can ensure that your Go code follows the standard import organization and helps to maintain a clean and consistent coding style.
