os/exec: the windows `route` command run failed with wrong output.

[iswarezwp]

The code:

package main

import (
    "fmt"
    "os/exec"
)

func main() {
    cmd := exec.Command("route", "ADD", "10.20.30.40", "MASK 255.255.255.255",
        "192.168.12.14")

    ret, err := cmd.CombinedOutput()
    if err != nil {
        fmt.Println(string(ret))
    }
}

I run this code under nomal and administrator model, and get the same result:

route:             192.168.12.14

Then I write some Python code:

import os

print(os.popen("route ADD 10.20.30.40 MASK 255.255.255.255 192.168.12.13").readlines()[0])

I got different result with different console model. And the output is just the same as I run the command directly.

wrong:

cmd := exec.Command("route", "ADD", "10.20.30.40", "MASK 255.255.255.255",
        "192.168.12.14")

correct:

cmd := exec.Command("route", "ADD", "10.20.30.40", "MASK", "255.255.255.255", "192.168.12.14")

wrong:

if err != nil {
   fmt.Println(string(ret))
}

correct:

if err != nil {
  panic(err)
}
fmt.Println(string(ret))

I think it's not a go's issue.

@hirochachacha I changed my code and the result is the same. Could you please run the test code on windows 7?

Sorry, It's my fault.
