Midori浏览器不会在脚本中第二次启动

Question

你好，我有一个apache服务器运行在我的Windows10PC上的xampp和一个RaspberryPi连接到它的脚本。脚本检查ist服务器是否在特定端口上可用，如果ist可用，启动浏览器，如果服务器不再可用，则关闭浏览器。这是我的剧本：

#!/bin/bash

### BEGIN INIT INFO
# Provides:          browerstartup.sh
# Required-Start:    
# Required-Stop:     
# Should-Start:      
# Should-Stop:       
# X-Start-Before:    
# X-Stop-After:      
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# X-Interactive:     
# Short-Description: If connection available, connecT!
# Description:       If connection is available on port 80: Then connect.
### END INIT INFO

server="192.168.16.74"
sleep=10

while [ true ] ; do
echo "Script start" >> /home/pi/browserlog
 midori=$(pgrep "midori")
 nc -w 5 -z $server 80 >/dev/null 2>&1
 if [ $? -ne 0 ] ; then
  echo "Server isnt running!" >> /home/pi/browserlog
  if [ $midori ] ; then
   echo "Midori is still running but server is offline: Killing midori"
   kill $midori
  fi
 else
  echo "Server is running!" >> /home/pi/browserlog
  if ! [ $midori ] ; then
   echo "Starting midori" >> /home/pi/browserlog
   midori -e Fullscreen -a http://$server/Website/t1&
  fi 
 fi
echo "Sleep $sleep" >> /home/pi/browserlog
 sleep $sleep
done

第一次启动and服务器时，它连接并启动midori，如果停止and服务器，则关闭midori。但是如果我再次启动网络服务器，它就不再启动midori了，我也不知道为什么.

这是我的browserlog文件：

Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start
Server is running!
Starting midori
Sleep 10
Script start

这里我手动停止了脚本！

也许你能帮我..。

我安装了midori并为您编写了一个新脚本:)

#!/bin/bash
