something like cat but done in go

cat.go

package main
import (
	"fmt"
	"io"
	"os"
)


func main () {
	v := os.Args[1:]
	var files []io.Reader = make([]io.Reader, len(v))
	var err error

	for key := range v {
		files[key], err = os.Open(v[key])
		if err != nil {
			return
		}
	}
	reader := io.MultiReader(files...)
	var buf = make([]byte, 1024)
	for {
		_, err := reader.Read(buf)
		if err != nil {
			break
		} else {
			fmt.Printf("%s", buf)
		}
	}
	fmt.Println()
}
