How to get the directory of the current executable file in Go?

Hello everyone! I'm a beginner Go developer and I've run into a problem: I need to determine the directory where the current executable file of my program is located. I'm writing a small CLI application that reads a configuration file located in the same folder as the binary. But when I run the program from a different directory (for example, via `go run` from the project root or from the system PATH), relative paths break. Here's what I've tried: ```go package main import ( "fmt" "os" "path/filepath" ) func main() { // Attempt 1: just os.Getwd() — gives the working directory, not the file's folder wd, _ := os.Getwd() fmt.Println("Working dir:", wd) // Attempt 2: os.Args[0] — shows the path used to call the program fmt.Println("Args[0]:", os.Args[0]) // Attempt 3 ```
