package main

import (

   "github.com/gomodule/redigo/redis"
)


func main(){
   conn,err:=redis.Dial("tcp","localhost:6379")
   if err!=nil{
      fmt.Println("conn reids error")
      return
   }
   defer conn.Close()

   conn.Send("MULTI")
   conn.Send("INCR","foo")
   conn.Send("INCR","bar")

   r,err:=conn.Do("EXEC")
   fmt.Println(r)
