1.日期作为变量当做文件名的一部分.
C:\Documents and Settings\Simon>echo %date%
2008-09-09 星期二C:\Documents and Settings\Simon>echo %date:~5,5%
09-09如果我们需要加入自订的分隔符,比如想要YYYY--MM--DD的格式,只需要分别取出YYYY, MM, DD再连接起来即可:
C:\Documents and Settings\Simon>echo %date:~0,4%--%date:~5,2%--%date:~8,2%2008--09—092.命令选择
C:\Users\hp>choice /c dme /m defrag,mem,end
defrag,mem,end [D,M,E]?D@echo off
choice /c dme /m defrag,mem,end if errorlevel 3 goto defrag (应先判断数值最高的错误码) if errorlevel 2 goto mem if errotlevel 1 goto end:defrag
c:dosdefrag goto end :mem mem goto end :end echo good bye3.错误判断
@net use /%1ipc$ %3 /u:"%2"
@if errorlevel 1 goto failed
4.组合命令
& Usage:第一条命令 & 第二条命令 [& 第三条命令...]
用这种方法可以同时执行多条命令,而不管命令是否执行成功
&& Usage:第一条命令 && 第二条命令 [&& 第三条命令...]
用这种方法可以同时执行多条命令,当碰到执行出错的命令后将不执行后面的命令,如果一直没有出错则一直执行完所有命令;
|| Usage:第一条命令 || 第二条命令 [|| 第三条命令...]
用这种方法可以同时执行多条命令,当碰到执行正确的命令后将不执行后面的命令,如果没有出现正确的命令则一直执行完所有命令;
