go语言简单的执行shell命令

package main

import(

"fmt"

"os/exec"

"os"

"strings"

)

func main(){

fmt.Println("shell")

var str,ip,data []byte

var err error

var cmd *exec.Cmd

cmd = exec.Command("whoami")

str,err = cmd.Output()

if err!=nil{

fmt.Println(err)

os.Exit(1)

}

fmt.Println(string(str))

fmt.Println("=======")

//filter line breaks

fmt.Println(strings.Trim(string(str),"\n"))

//get IP ,Mac platform,can not implement

fmt.Println("=======")

cmd = exec.Command("/bin/sh", "-c", `/sbin/ifconfig en0 | grep -E 'inet ' | awk '{print $2}'`)

ip,err = cmd.Output()

if err!=nil{

fmt.Println(err)

os.Exit(1)

}

fmt.Println(string(ip))

fmt.Println(strings.Trim(string(ip),"\n"))

//implement command

fmt.Println("====================")

cmd = exec.Command("/bin/sh","-c","echo wo shi shui wo zai na")

data,err = cmd.Output()

if err!=nil{

fmt.Println(err)

os.Exit(1)

}

fmt.Println(string(data))

fmt.Println(strings.Trim(string(data),"\n"))

}
