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

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。
