在Windows (Windows XP)批处理脚本中,我需要格式化当前日期和时间,以便以后在文件名等中使用。
这类似于堆栈溢出问题如何在批处理文件中添加日期,但也包含时间。
到目前为止,我有这个:
echo %DATE%
echo %TIME%
set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__%time:~0,2%_%time:~3,2%_%time:~6,2%
echo %datetimef%
这使:
28/07/2009
8:35:31.01
2009_07_28__ 8_36_01
是否有一种方法可以允许%TIME%中的个位数小时,以便我可以得到以下结果?
2009_07_28__08_36_01
这个bat文件(保存为datetimestr.bat)生成3次datetime字符串:(1)长datetime字符串,包含星期几和秒,
(2)短的datetime字符串没有它们和
(3)短版代码。
@echo off
REM "%date: =0%" replaces spaces with zeros
set d=%date: =0%
REM "set yyyy=%d:~-4%" pulls the last 4 characters
set yyyy=%d:~-4%
set mm=%d:~4,2%
set dd=%d:~7,2%
set dow=%d:~0,3%
set d=%yyyy%-%mm%-%dd%_%dow%
set t=%TIME: =0%
REM "%t::=%" removes semi-colons
REM Instead of above, you could use "%t::=-%" to
REM replace semi-colons with hyphens (or any
REM non-special character)
set t=%t::=%
set t=%t:.=%
set datetimestr=%d%_%t%
@echo Long date time str = %datetimestr%
set d=%d:~0,10%
set t=%t:~0,4%
set datetimestr=%d%_%t%
@echo Short date time str = %datetimestr%
@REM Short version of the code above
set d=%date: =0%
set t=%TIME: =0%
set datetimestr=%d:~-4%-%d:~4,2%-%d:~7,2%_%d:~0,3%_%t:~0,2%%t:~3,2%%t:~6,2%%t:~9,2%
@echo Datetimestr = %datetimestr%
pause
为了给予适当的赞扬,我将彼得·莫滕森(Peter Mortensen)(14年6月18日21:02)和欧佩罗(opello)(8月25日至11日14:27)的概念融合在一起。
您可以写得更短,但是这个长版本使阅读和理解代码变得更容易。
在这种情况下,使用简单、标准的编程方法:
与其花费大量精力解析未知实体,不如简单地保存当前配置,将其重置为已知状态,提取信息,然后恢复原始状态。只使用标准的Windows资源。
具体来说,日期和时间格式存储在注册表项下
HKCU\Control Panel\International\ [MS定义]"values": " timeformat "及"sShortDate"。
Reg是包含在所有Windows版本中的控制台注册表编辑器。
修改HKCU密钥不需要提升权限
Prompt $N:$D $T$G
::Save current config to a temporary (unique name) subkey, Exit if copy fails
Set DateTime=
Set ran=%Random%
Reg copy "HKCU\Control Panel\International" "HKCU\Control Panel\International-Temp%ran%" /f
If ErrorLevel 1 GoTO :EOF
::Reset the date format to your desired output format (take effect immediately)
::Resetting the time format is useless as it only affect subsequent console windows
::Reg add "HKCU\Control Panel\International" /v sTimeFormat /d "HH_mm_ss" /f
Reg add "HKCU\Control Panel\International" /v sShortDate /d "yyyy_MM_dd" /f
::Concatenate the time and (reformatted) date strings, replace any embedded blanks with zeros
Set DateTime=%date%__%time:~0,2%_%time:~3,2%_%time:~6,2%
Set DateTime=%DateTime: =0%
::Restore the original config and delete the temp subkey, Exit if restore fails
Reg copy "HKCU\Control Panel\International-Temp%ran%" "HKCU\Control Panel\International" /f
If ErrorLevel 1 GoTO :EOF
Reg delete "HKCU\Control Panel\International-Temp%ran%" /f
简单,直接,应该适用于所有地区。
出于我不理解的原因,重置“sShortDate”值立即生效
一个控制台窗口,但重置非常相似的“sTimeFormat”值不会生效
直到打开一个新的控制台窗口。但是,唯一可以更改的是分隔符-
数字的位置是固定的。同样,“HH”时间标记应该在前导零之前,但它没有。
幸运的是,变通方法很简单。
这个批处理脚本将完全按照O.P.的要求执行(在Windows XP SP3上测试)。
我还使用了前面“jph”所描述的聪明的注册表技巧,我认为这是在任何新的或旧的Windows系统上获得100%一致的日期格式“yyyy_MM_dd”的最简单方法。对一个注册表值的更改是瞬时、临时和微不足道的;它只持续几毫秒,然后立即恢复。
双击此批处理文件进行即时演示,命令提示符窗口将弹出并显示您的时间戳. . . . .
