更新:现在是2016年,我将使用PowerShell,除非有一个真正令人信服的向后兼容的原因,特别是因为使用日期的区域设置问题。参见@npocmaka的https://stackoverflow.com/a/19799236/8479


什么是Windows命令行语句(s),我可以使用以我可以放入文件名的格式获取当前日期时间?

我想要一个.bat文件,它将一个目录压缩成一个归档文件,其中当前日期和时间作为名称的一部分,例如Code_2008-10-14_2257.zip。有什么简单的方法可以做到这一点,独立于机器的区域设置吗?

我真的不介意日期格式,理想情况下它是yyyy-mm-dd,但任何简单的都可以。

到目前为止,我已经得到了这个,在我的机器上给我Tue_10_14_2008_230050_91:

rem Get the datetime in a format that can go in a filename.
set _my_datetime=%date%_%time%
set _my_datetime=%_my_datetime: =_%
set _my_datetime=%_my_datetime::=%
set _my_datetime=%_my_datetime:/=_%
set _my_datetime=%_my_datetime:.=_%

rem Now use the timestamp by in a new ZIP file name.
"d:\Program Files\7-Zip\7z.exe" a -r Code_%_my_datetime%.zip Code

我可以接受这个,但它似乎有点笨重。理想情况下,它应该更简短,并具有前面提到的格式。

我用的是Windows Server 2003和Windows XP Professional。我不想安装额外的实用程序来实现这一点(尽管我知道有一些工具可以很好地格式化日期)。

这并不是真的更简短,但可能是一种更灵活的方式(来源):

FOR /F "TOKENS=1* DELIMS= " %%A IN ('DATE/T') DO SET CDATE=%%B
FOR /F "TOKENS=1,2 eol=/ DELIMS=/ " %%A IN ('DATE/T') DO SET mm=%%B
FOR /F "TOKENS=1,2 DELIMS=/ eol=/" %%A IN ('echo %CDATE%') DO SET dd=%%B
FOR /F "TOKENS=2,3 DELIMS=/ " %%A IN ('echo %CDATE%') DO SET yyyy=%%B
SET date=%mm%%dd%%yyyy%

其他回答

我用vMax的批处理文件更改了答案,所以它也适用于荷兰语。 荷兰语(尽管我们是持久性的)在%date%、date/t和date中有一些更改,这些更改破坏了原始的批处理文件。

如果有些人也能检查其他Windows locale,并报告结果,那就太好了。 如果批处理文件在您的位置失败,那么请在命令提示符中包含这两个语句的输出: 回音:^ |日期 日期/ t

这是你应该从批处理文件中得到的输出示例:

C:\temp>set-date-cmd.bat
Today is Year: [2011] Month: [01] Day: [03]
20110103

以下是修改后的代码及其原因:

:: Works on any NT/2k machine independent of regional date settings
::
:: 20110103 - adapted by jeroen@pluimers.com for Dutch locale
:: Dutch will get jj as year from echo:^|date, so the '%%c' trick does not work as it will fill 'jj', but we want 'yy'
:: luckily, all countries seem to have year at the end: http://en.wikipedia.org/wiki/Calendar_date
::            set '%%c'=%%k
::            set 'yy'=%%k
::
:: In addition, date will display the current date before the input prompt using dashes
:: in Dutch, but using slashes in English, so there will be two occurances of the outer loop in Dutch
:: and one occurence in English.
:: This skips the first iteration:
::        if "%%a" GEQ "A"
::
:: echo:^|date
:: Huidige datum: ma 03-01-2011
:: Voer de nieuwe datum in: (dd-mm-jj)
:: The current date is: Mon 01/03/2011
:: Enter the new date: (mm-dd-yy)
::
:: date/t
:: ma 03-01-2011
:: Mon 01/03/2011
::
:: The assumption in this batch-file is that echo:^|date will return the date format
:: using either mm and dd or dd and mm in the first two valid tokens on the second line, and the year as the last token.
::
:: The outer loop will get the right tokens, the inner loop assigns the variables depending on the tokens.
:: That will resolve the order of the tokens.

这是时间部分的类似批处理文件。

查看Windows批处理文件(.bat)以MMDDYYYY格式获取当前日期:

@echo off
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%c-%%a-%%b)
For /f "tokens=1-2 delims=/:" %%a in ('time /t') do (set mytime=%%a%%b)
echo %mydate%_%mytime%

如果你更喜欢24小时/军事格式的时间,你可以用这个替换第二个FOR行:

For /f "tokens=1-2 delims=/:" %%a in ("%TIME%") do (set mytime=%%a%%b)

C: \ date.bat > 2008 - 10 - 14 - _0642

如果你想要日期独立于地区日/月顺序,你可以使用“WMIC os GET LocalDateTime”作为源,因为它是ISO顺序:

@echo off
for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE 2^>NUL`) do if '.%%i.'=='.LocalDateTime.' set ldt=%%j
set ldt=%ldt:~0,4%-%ldt:~4,2%-%ldt:~6,2% %ldt:~8,2%:%ldt:~10,2%:%ldt:~12,6%
echo Local date is [%ldt%]

C: > test.cmd 本地日期为[2012-06-19 10:23:47.048]

生成ISO日期格式的区域独立解决方案:

rem save the existing format definition
for /f "skip=2 tokens=3" %%a in ('reg query "HKCU\Control Panel\International" /v sShortDate') do set FORMAT=%%a
rem set ISO specific format definition
reg add "HKCU\Control Panel\International" /v sShortDate /t REG_SZ /f /d yyyy-MM-dd 1>nul:
rem query the date in the ISO specific format 
set ISODATE=%DATE%
rem restore previous format definition
reg add "HKCU\Control Panel\International" /v sShortDate /t REG_SZ /f /d %FORMAT% 1>nul:

还有什么可以优化的: 如果在修改日期格式的短时间内使用日期格式,其他进程可能会感到困惑。因此,根据现有的格式字符串解析输出可能会“更安全”——但会更复杂

另一种方法(credit):

@For /F "tokens=2,3,4 delims=/ " %%A in ('Date /t') do @( 
    Set Month=%%A
    Set Day=%%B
    Set Year=%%C
)

@echo DAY = %Day%
@echo Month = %Month%
@echo Year = %Year%

请注意,我在这里的答案仍然依赖于日期和月份的顺序,由区域设置决定-不知道如何解决这个问题。
