Go语言执行系统命令行命令的方法

本文实例讲述了Go语言执行系统命令行命令的方法。分享给大家供大家参考。具体如下：

执行Go代码时可以附加参数，包括要执行的命令和给命令的参数

复制代码 代码如下: package main

import (

  "os"

  "os/exec"

  "fmt"

  "flag"

  "strings"

)

func main() {

  command := flag.String("cmd", "pwd", "Set the command.")

  args := flag.String("args", "", "Set the args. (separated by spaces)")

  flag.Usage = func() {

    fmt.Fprintf(os.Stderr, "Usage: %s [-cmd <command>] [-args <the arguments (separated by spaces)>]\n", os.Args[0])

    flag.PrintDefaults()

  }

  flag.Parse()

  fmt.Println("Command: ", *command)

  fmt.Println("Arguments: ", *args)

  var argArray []string

  if *args != "" {

    argArray = strings.Split(*args, " ")

  } else {

    argArray = make([]string, 0)

  }

  cmd := exec.Command(*command, argArray...)

  buf, err := cmd.Output()

  if err != nil {

      fmt.Fprintf(os.Stderr, "The command failed to perform: %s (Command: %s, Arguments: %s)", err, *command, *args)

      return

  }

   fmt.Fprintf(os.Stdout, "Result: %s", buf)

}

希望本文所述对大家的Go语言程序设计有所帮助。
