The command gofmt -s -w ${source-go} is used to format Go source code files by applying the official Go formatting rules. Here is an explanation of the different components of the command:

• gofmt is the command used to format Go source code files.
• -s is a flag that enables the simplification of code by applying additional rules. For example, it might remove unnecessary parentheses or simplify if statements.
• -w is a flag that instructs gofmt to write the formatted code back to the file instead of printing it to the standard output.

${source-go} is a placeholder for the path or paths to the Go source code file(s) you want to format. You should replace it with the actual file or directory path(s) of the Go code you want to format.

To summarize, the command executes the gofmt tool with specific flags to format the Go source code files and automatically overwrite the original files with the formatted version.
