First implementation of a file copy program written in Go

fcopy.go

package main

import (
	"io/ioutil"
	"log"
	"os"
)

func fcopy(src, dst string) {
	content, err := ioutil.ReadFile(src)
	if err != nil {
		log.Fatal(err)
	}
	err = ioutil.WriteFile(dst, content, 0777)
	if err != nil {
		log.Fatal(err)
	}
	log.Printf("Successfully copied contens of %s to %s", src, dst)
}

func main() {
	if l := len(os.Args); l != 3 {
		log.Printf("Usage: fcopy <src file> <dst file>")
	} else {
		fcopy(os.Args[1], os.Args[2])
	}
}
