go - fmt.Scanf does not consume all the characters through the end of the string

Question

package main
import "fmt"

func main(){
    var i int
    fmt.Print("input integer: ")
    fmt.Scanf("%d", &i)

}

when I run this small program from terminal and give input as

input integer: 3.ls

it also executes ls command or when i give input

input integer: 665.cd someDir

it executes cd someDir. Is this normal behavior with Scanf in go.This does not happen in C. Can someone explain what's happening.
