How to access command-line arguments passed to a Go program?

Question

How do I access command-line arguments in Go? They\'re not passed as arguments to main.

A complete program, possibly created by linking m

Answer 1

You can access the command-line arguments using the os.Args variable. For example,

package main

import (
    "fmt"
    "os"
)

func main() {
    fmt.Println(len(os.Args), os.Args)
}

You can also use the flag package, which implements command-line flag parsing.
