pkill有的时候并不能杀死进程？

pkill的用法：http://man.linuxde.net/pkill

根据进程命令行，杀死进程

如下intellij.go代码为一个代理服务器，把本地请求转向一个代理

package main

import (
    "flag"
    "log"
    "net/http"
    "net/http/httputil"
    "net/url"
)

type handle struct {
    reverseProxy string
}

func (this *handle) ServeHTTP(w http.ResponseWriter, r *http.Request) {
    remote, err := url.Parse(this.reverseProxy)
    if err != nil {
        log.Fatalln(err)
    }
    proxy := httputil.NewSingleHostReverseProxy(remote)
    r.Host = remote.Host
    proxy.ServeHTTP(w, r)
    log.Println(r.RemoteAddr + " " + r.Method + " " + r.URL.String() + " " + r.Proto + " " + r.UserAgent())
}

func main() {
    bind := flag.String("l", "0.0.0.0:8888", "listen on ip:port")
    remote := flag.String("r", "http://idea.imsxm.com:80", "reverse proxy addr")
    flag.Parse()
    log.Printf("Listening on %s, forwarding to %s", *bind, *remote)
    h := &handle{reverseProxy: *remote}
    err := http.ListenAndServe(*bind, h)
    if err != nil {
        log.Fatalln("ListenAndServe: ", err)
    }
}
