简化常用指令操作，写个脚本
比如设置环境变量和scp往机器中拷贝文件，整个脚本简化下操作，省得重复敲不少命令
#!/bin/bash source /opt/myir-imx-fb-qt5/4.1.15-2.0.1/environment-setup-cortexa7hf-neon-poky-linux-gnueabi scp myapp root@192.168.79.1:/app/my_app/bin
或者是启动应用，手动执行可能还得进入某个目录或设置环境变量，写一个脚本搞定：
run_app.sh
#!/bin/bash export LD_LIBRARY_PATH=/app/city_app/lib/ echo $LD_LIBRARY_PATH cd /app/city_app/bin/ ./b503_app
查找应用并设置应用的环境变量并运行
run_app.sh
应用升级脚本
start_remoteupdate.sh
#!/bin/bash singelName="remoteupdate" fileName="/usr/bin/remoteupdate" configFile="/app/update.conf" function CheckProcess() { PROCESS_NUM=`ps | grep "$1" | grep -v "grep" | wc -l` return $PROCESS_NUM } function startProcess() { echo "check process run status" CheckProcess $singelName if [ $? -eq 0 ];then echo "progress is not run" else echo "process is running" #killall -9 $singelName #sleep 1 exit 0 fi echo "start remoteupdate ..." $singelName & echo "start end" } #copy config file if [ -f $configFile ];then echo "config file exist" else echo "copy update.conf file" cp /app/city_app/opt/update.conf /app/ sync if [ -f $configFile ];then echo "copy ok" fi fi #start process remoteupdate if [ ! -f $fileName ];then echo "copy remoteupdate process to /usr/bin" cp /app/city_app/opt/$singelName /usr/bin/ sync if [ -f $fileName ];then echo "copy ok" startProcess exit 0 else echo "copy fail" exit 1 fi else echo "remoteupdate file exsit" startProcess exit 0 fi
应用监控和升级服务脚本
app_monitor.sh
#!/bin/bash #######city app monitor deamon ######## function checkAppRun() { flag=0 val=0 cnt=0 max=$2 #echo "checkApprun...$1" while [ $val -lt $max ] do cnt=$(ps | grep $1 | wc -l) if [ $cnt -le 1 ]; then let flag+=1 sleep 1 let val+=1 else break fi done if [ $flag -ge $max ]; then return 0 #$1 app is not running else return 1 #$1 app has been run fi } function CheckProcess() { PROCESS_NUM=`ps | grep "$1" | grep -v "grep" | wc -l` return $PROCESS_NUM } function monitor_app() { while true do CheckProcess b503_app if [ $? -ne 1 ] ; then if [ $? -ne 0 ]; then killall -9 b503_app fi source /etc/init.d/app_update_b503_app.sh fi # CheckProcess remoteupdate # if [ $? -ne 1 ] ; # then # if [ $? -ne 0 ]; # then # killall -9 remoteupdate # fi # source /etc/init.d/app_start_remoteupdate.sh # fi done } function monitor_b503_ft() { while true do CheckProcess b503_ft if [ $? -eq 0 ] ; then break else sleep 1 fi done } function monitor_ft_app() { while true do checkAppRun b503_ft 2 if [ $? -eq 0 ] ; then break fi done } ################main##################### ####synchronize date and rtc time####### #date #hwclock -w --local ######################################## source /etc/init.d/app_update_b503_ft.sh #monitor_ft_app & checkAppRun b503_ft 2 if [ $? -eq 0 ] ; then source /etc/init.d/app_update_b503_app.sh monitor_app & else monitor_b503_ft source /etc/init.d/app_update_b503_app.sh monitor_app & fi
应用ipk包安装脚本
