基本使用界面大概是这样
我的构思将其分成7个部分
1、定义了函数
#<-----------------------询问继续使用工具箱函数定义
whether () { read -p "Continue to use[y],sign out[n]:" play
if [[ "$play" == "y" ]];then
clear
else
echo "Thank you for your use. Have a nice day!";exit
fi
}
#<-------------------------菜单显示函数定义
ToolboxMenu () {
echo -e "\033[5;34m ========This is a system detection toolbox============\033[0m"
echo -e "\033[33m | 1.查看磁盘挂载信息 | \033[0m"
echo -e "\033[33m | 2.查看内存信息 | \033[0m"
echo -e "\033[33m | 3.查看CPU信息 | \033[0m"
echo -e "\033[33m | 4.查看网络端口信息 | \033[0m"
echo -e "\033[33m | 5.查看进程信息 | \033[0m"
echo -e "\033[33m | 6.磁盘每秒进程下的I0读写数量 | \033[0m"
echo -e "\033[33m | 7.Exit Toolbox | \033[0m"
echo -e "\033[33m | Current Time:$(date "+%Y-%m-%d %H:%M:%S") welcome!!engineer! |\033[0m"
echo -e "\033[5;34m =============System detection toolbox=================\033[0m"
}
2、使用交互定义变量邀请用户输入
#<----------------邀请用户输入需要检测的信息
read -p "Please enter your choice![1..7]" number
3、使用while循环让工具箱一直使用
4、中间为case判断选项
5、最后一部分为没有匹配项的匹配
#<------------------没有匹配项重新显示菜单
*)
echo -e "\033[31m Error redirecting to menu for you ! \033[0m"
