Running Multiple Go Files in a Package from the Command Line

As a Go newcomer, it's understandable to face challenges when your program size increases and you need to divide it into multiple files. Running them all at once can be a pain, especially when you have a large number of files.

The initial attempt of using go run main.go for each file individually becomes cumbersome. However, you can simplify the process by utilizing the .go convention.

Here's the Solution:

Instead of specifying each file, you can simply run:

go run .

This command will automatically run all the .go files within the current directory, effectively treating them as a package. It also eliminates the need to worry about the main function location.

Explanation:

The special character . in the command represents the current directory. By using go run ., you are instructing the compiler to run all the Go files (ending in .go) in the current directory. The compiler will automatically detect the main() function and execute the program accordingly.

This method streamlines the process of running multiple files in a package, saving you time and frustration.
