批处理中使用vbs

批处理中使用vbs

1 列举自启动的服务

@echo for each sc in getobject("winmgmts:\\.\root\cimv2:win32_service").instances_ >sc.vbs
@echo if sc.startmode="Auto" then wscript.echo sc.name^&" - "^&sc.pathname >>sc.vbs
@echo next >>sc.vbs & cscript //nologo sc.vbs & del sc.vbs

2 列举正在运行的服务

@echo for each sc in getobject("winmgmts:\\.\root\cimv2:win32_service").instances_ >sc.vbs
@echo if sc.state="Running" then wscript.echo sc.name^&" - "^&sc.pathname >>sc.vbs
@echo next >>sc.vbs & cscript //nologo sc.vbs & del sc.vbs

3 显示系统最后一次启动的时间

@echo for each os in getobject _ >bt.vbs
@echo ("winmgmts:\\.\root\cimv2:win32_operatingsystem").instances_ >>bt.vbs
@echo wscript.echo os.lastbootuptime:next >>bt.vbs & cscript //nologo bt.vbs & del bt.vbs

显示结果的格式是：
yyyymmddHHMMSS******ZZZZ
_年_月日时分秒_微秒_时区

变形为获取系统的时区
@echo for each os in getobject _ >bt.vbs
@echo ("winmgmts:\\.\root\cimv2:win32_operatingsystem").instances_ >>bt.vbs
@echo wscript.echo os.lastbootuptime:next >>bt.vbs & cscript //nologo bt.vbs >tempTime.txt & del bt.vbs

SET /p LastBootUpTime=<tempTime.txt & del tempTime.txt
SET TimeZone=%LastBootUpTime:~21%

4 利用vbs进行浮点运算
@echo off
set a=8.878
set b=9.4

echo aa=%a%>hero.vbs
echo bb=%b%>>hero.vbs
echo sum=aa+bb>>hero.vbs
echo msgbox sum>>hero.vbs

call hero.vbs
del hero.vbs
pause

完！
