How Can I Run Multiple Go Files Simultaneously from the Command Line?

Executing Multiple Go Files Simultaneously from the Command Line

When working with Go programs that span multiple files, running the main function from a single file can be tedious if you have to explicitly specify each additional file. This issue commonly arises for beginners who are new to Go's package system.

However, there's a convenient solution to this problem. Instead of manually listing all the required files, you can use the special command:

go run .

This command will automatically discover and run all the .go files within the current directory. This is possible because Go recognizes the current directory as a package, and it will look for a main function within that package.

Example:

Consider the following directory structure:

mypackage/    # Current working directory
├── main.go  # File containing the main() function
├── file1.go
├── file2.go

To execute all the files in this directory, simply navigate to the mypackage directory and run:

go run .

This command will compile and run the program, effectively executing all the Go files in the current directory.

This approach eliminates the need to manually specify each file and provides a more convenient way to execute Go programs that span multiple files.
