【常用脚本记录1----挂测问题脚本】

脚本1：

用于测试重启后识别hostapd两个进程，如果当前正常识别到两个进程，则重启设备，重复进行识别进程，知道进程识别有误之后，会退出，往text.txt内写入识别异常的时间

#!/bin/sh
sleep 30
count=`ps | grep hostapd | grep -v grep | wc -l`
#echo "sssss $count"
if [ $count -eq 2 ];then
    echo "Now rebooting .................."
   reboot
#  echo "$date The wlan abnormal!!" > /text.txt
fi

echo "$date The wlan abnormal!!" > /text.txt

 

脚本2：

记录一开始reload的时间，拨号成功后记录时间重新reload

判断拨号成功的方法：获取当前的ip地址的第一个数字，如果和1相等，则当前拨号成功

 

 

#!/bin/sh
dial_time=""
up_time=""
function cellular_dial()
{
        echo -e "enable\ncon t\ncellular reload" | vtysh
    sleep 10
}

function wait_cellular_up()
{
        dial_time=`cat /proc/uptime  | awk '{print $1}' | cut -d '.' -f1`
    dial_date=`date`
        while [ 1 ]                                                        
        do
        test=`ifconfig cellular0 | grep Bcast | sed 's/^.*addr://g' | sed 's/Bcast.*$//g' | sed 's/\./ /g' | awk '{print $1}'`
        a=1
        cellip=${test:0:1}
        if [ "$cellip" = "$a" ]; then                                                             
            break
        fi
        sleep 1
    done                                                                
    up_time=`cat /proc/uptime  | awk '{print $1}' | cut -d '.' -f1`
    up_date=`date`
    echo "$dial_date $up_date"
}                                                      
                                                       
function print_up_duration()                           
{                                                      
        duration_time=`expr $up_time - $dial_time`     
        echo "cellular reload duration: $duration_time"
}                       
                         
while :                  
do                       
        cellular_dial    
        wait_cellular_up 
        print_up_duration
done

 

 

脚本3：

用于在vtysh底下对当前的进程开关，如果有进程在，则关闭当前进程重启hostapd进程后查看dmesg中是否有异常打印，有异常打印则跳出循环

将进程名作为传递过来的一个参数来使用

运行的时候要在脚本后面带上一个参数 为./wlan.sh  wlan0

#!/bin/sh
rebootcount=1
echo $1
while [ 1 ]
do
        wlancount=`ps | grep hostapd | grep -v grep | wc -l`
        if [ $wlancount -eq 1 ];then
                echo -e "en\ncon t\ninterface $1\nshutdown\nend\nwrite" | vtysh
                #echo -e "en\ncon t\ninterface p2p0\nshutdown\nend\nwrite" | vtysh
                echo "---------run restarthostapd count: $rebootcount"
                let rebootcount=rebootcount+1
                echo -e "en\ncon t\ninterface $1\nno shutdown\nend\nwrite" | vtysh
               #echo -e "en\ncon t\ninterface p2p0\nno shutdown\nend\nwrite" | vtysh
        fi
        echo "=====start sleep===="
        sleep 40
        echo "=====stop sleep===="
        flag_err=`dmesg | grep "hif_sdio_check_fw_reg: fw indication is 0x0." | wc -l`
        flag=`dmesg | grep "dump_backtrace" | wc -l`
        echo "===enter===:$flag"

               if [ $flag_err -gt 0 ] || [ $flag -gt 0 ];then
                       echo ".....wifi error!!!!!!!!!!!!!!"
                       break;
                fi

done

 

脚本4：

找到某个进程然后杀掉当前进程，查看守护进程将其启动后的 dmesg信息 是否会有报错信息（kill -9 是发送一个强制杀掉进程的信号 ）

#!/bin/sh
rebootcount=1
while [ 1 ]
do
      # wlanid=`ps | grep hostapd | grep -v grep | awk '{print $1}'`
        wlanid=`ps | grep "hostapd.conf.wlan0" | grep -v grep | awk '{print $1}'`
        p2p0id=`ps | grep "hostapd.conf.p2p0" | grep -v grep | awk '{print $1}'`
        wlancount=`ps | grep hostapd | grep -v grep | wc -l`
        if [ $wlancount -eq 2 ];then
                echo "--WlanPID--"
                echo $wlanid  $p2p0id
                echo "--wlanCount--"
                echo $wlancount
                kill -9 $wlanid
                kill -9 $p2p0id
                rm /var/run/hostapd.p2p0
                rm /var/run/hostapd.wlan0
                echo "---------run reboot count: $rebootcount"
                let rebootcount=rebootcount+1
        fi
           echo "=====start sleep===="
           sleep 50
           echo "=====stop sleep===="
           flag_err=`dmesg | grep "hif_sdio_check_fw_reg: fw indication is 0x0." | wc -l`
           flag_err1=`dmesg | grep "dump_backtrace" | wc -l`
           if [ $flag_err -gt 0 || flag_err1 -gt 0 ];then
                echo ".....wifi error!!!!!!!!!!!!!!"
                break;
           fi
done

 

 

查询路由器当前蜂窝模块温度和CPU 温度

#!/bin/sh
while [ 1 ]
do
cat /sys/devices/virtual/thermal/thermal_zone0/temp  >> /var/log/message
vtysh -c enable -c "con t" -c "cellular send at "at+qtemp"" 
sleep 10
done

上面一个是查询当前的CPU温度 下面是查询移远的蜂窝模块温度

如果是查询泰利特模块温度 则后面改成 cellular send at "AT#TEMPMON=1"

 

当前打印出来的温度  蜂窝模块的温度是在AT指令返回值的最后一个值 才会蜂窝模块的温度 

温度到达极限值时 log中会打印出相关的内容 表示当前的温度已经超过一定的值
