Getting current process PID

获取程序的pid很有用

拿到pid之后，你就可以使用操作系统自带的命令来查看更多关于这个pid的信息, eg

ps -p pid -v
package main

import (
  "fmt"
  "os"
  "os/exec"
  "strconv"
)

func main() {

  pid := os.Getpid()
  fmt.Printf("Process PID: %d \n", pid)

  prc := exec.Command("ps", "-p", strconv.Itoa(pid), "-v")
  out, err := prc.Output()
  if err != nil {
    panic(err)
  }

  fmt.Println(string(out))

}
