为bat脚本增加选择，来简化脚本

1、输出选择项：rem this is to for user to choose:choiceecho #############垆杪屑丝###################################echo ##this is a choice exampleecho ##choose:echo ## A=choose Aecho ## B=choose Becho ## C=choose Cecho ## D=choose Decho ## q=exit:echo ##echo ################################################

2、获取终端输入信息：set /P action=pls choose your action:if /I "%action%"=="A" goto ActionA...if /I "%action%"=="q" goto quit

3、根据终端输入的不同信息，实现不同的动作：:ActionAecho your choosed Agoto choice...:quitecho existing ..pauseexit

4、美化脚本，最终显示：@echo offrem this is to for user to choose:choiceecho #################垆杪屑丝###############################echo ##this is a choice exampleecho ##choose:echo ## A=choose Aecho ## B=choose Becho ## C=choose Cecho ## D=choose Decho ## q=exit:echo ##echo ################################################rem check the choice infoset /P action=pls choose your action:if /I "%action%"=="A" goto ActionAif /I "%action%"=="B" goto ActionBif /I "%action%"=="C" goto ActionCif /I "%action%"=="D" goto ActionDif /I "%action%"=="q" goto quit:ActionAecho your choosed Agoto choice:ActionBecho your choosed Bgoto choice:ActionCecho your choosed Cgoto choice:ActionDecho your choosed Dgoto choice:quitecho existing ..pauseexit
