windows - 无论区域设置如何，在批处理文件中拆分 %date%

Question

有没有办法%date%在批处理文件中拆分（例如，在 3 个环境变量中），但不管区域设置如何？今天的日期3/13/2013适用于美国，但使用我的区域设置是13.3.2013-分隔符已更改，顺序也已更改。

Answer 1

四年过去了，但这个问题并没有变老，我认为现在有一个比使用 wmic 更好的答案（在 win7 上）。

for /F "tokens=1,2,3 delims=_" %%i in ('PowerShell -Command "& {Get-Date -format "MM_dd_yyyy"}"') do (
    set MONTH=%%i
    set DAY=%%j
    set YEAR=%%k
)
echo %MONTH% %DAY% %YEAR%

使用 powershell Get-Date，您可以微调所需的格式（短、长、数字、名称等）。在此示例中，“MM_dd_yyyy”将为您提供一个带有前导零的数字日期，以防单个数字月或日

Answer 2

您可以使用 wmic来完成（但 WMIC 不包含在 XP Home 中）：

@ECHO OFF
:: Check WMIC is available
WMIC.EXE Alias /? >NUL 2>&1 || GOTO s_error

:: Use WMIC to retrieve date and time
FOR /F "skip=1 tokens=1-6" %%G IN ('WMIC Path Win32_LocalTime Get Day^,Hour^,Minute^,Month^,Second^,Year /Format:table') DO (
   IF "%%~L"=="" goto s_done
      Set _yyyy=%%L
      Set _mm=00%%J
      Set _dd=00%%G
      Set _hour=00%%H
      SET _minute=00%%I
)
:s_done

:: Pad digits with leading zeros
      Set _mm=%_mm:~-2%
      Set _dd=%_dd:~-2%
      Set _hour=%_hour:~-2%
      Set _minute=%_minute:~-2%

:: Display the date/time in ISO 8601 format:
Set _isodate=%_yyyy%-%_mm%-%_dd% %_hour%:%_minute%
Echo %_isodate%

GOTO:EOF

:s_error
Echo GetDate.cmd
Echo Displays date and time independent of OS Locale, Language or date format.
Echo Requires Windows XP Professional, Vista or Windows 7
Echo.
Echo Returns 6 environment variables containing isodate,Year,Month,Day,hour and minute.

您可以通过解析 date 命令来查找当前所需的日期格式。

第一个链接表明您可能需要在 Win7 上编辑第二个链接中的代码，以处理短日期/长日期表单周围的一些额外皱纹。

Answer 3

我已经修改了sashoalm's version 以处理被抑制的前导零情况：

@Echo OFF
SETLOCAL
If "%Date%A" LSS "A" (Set _NumTok=1-3) Else (Set _NumTok=2-4)
:: Default Delimiter of TAB and Space are used
For /F "TOKENS=2*" %%A In ('REG QUERY "HKCU\Control Panel\International" /v iDate') Do Set _iDate=%%B
For /F "TOKENS=2*" %%A In ('REG QUERY "HKCU\Control Panel\International" /v sDate') Do Set _sDate=%%B
IF %_iDate%==0 For /F "TOKENS=%_NumTok% DELIMS=%_sdate% " %%F In ("%Date%") Do CALL :procdate %%H %%F %%G
IF %_iDate%==1 For /F "TOKENS=%_NumTok% DELIMS=%_sdate% " %%F In ("%Date%") Do CALL :procdate %%H %%G %%F
IF %_iDate%==2 For /F "TOKENS=%_NumTok% DELIMS=%_sdate% " %%F In ("%Date%") Do CALL :procdate %%F %%G %%H
endlocal&SET YYYYMMDD=%YYYYMMDD%
GOTO :eof

::
:: Date elements are supplied in Y,M,D order but may have a leading zero
::
:procdate
:: if single-digit day then 1%3 will be <100 else 2-digit
IF 1%3 LSS 100 (SET YYYYMMDD=0%3) ELSE (SET YYYYMMDD=%3)
:: if single-digit month then 1%2 will be <100 else 2-digit
IF 1%2 LSS 100 (SET YYYYMMDD=0%2%YYYYMMDD%) ELSE (SET YYYYMMDD=%2%YYYYMMDD%)
:: Similarly for the year - I've never seen a single-digit year
IF 1%1 LSS 100 (SET YYYYMMDD=20%YYYYMMDD%) ELSE (SET YYYYMMDD=%1%YYYYMMDD%)
GOTO :eof

根据您的意愿返回 YYYYMMDD - 子字符串。

有趣的是，插入之后SETLOCAL

IF NOT "%1"=="" set date=%1

将允许将本地序列中的任何日期（没有日期名称）解码为 YYYYMMDD（但请注意 yy 形式提供的 19xx 日期将显示为 20xx - 如果您认为有必要，可以轻松补偿）

我对 robocopy 有一个额外的建议：

@echo off &setlocal enabledelayedexpansion
set "day="
for /f "tokens=3,4,8skip=4delims=: " %%i in ('robocopy') do if not defined day (
    set "month=%%i"
    set "day=0%%j"
    set "year=%%k"
)
set /a cnt=0
for %%i in (Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec) do (
    set /a cnt+=1
    if "%%i"=="%month%" set "month=0!cnt!"
)
set "day=%day:~-2%"
set "month=%month:~-2%"
echo.%day%.%month%.%year%
endlocal

Answer 5

试试这个：Set_date.cm

@echo off&goto :start
:Set_Date DateEnv [Date] or [/p="Prompt for Date: "] [/r]
echo.
echo.Usage: Set_Date.cmd DateEnv [Date] or [/p="Prompt for Date: "]
echo.Populates date variables labeled: 'DateEnv_???', see below
echo.Accepted date formats:
echo.        m-d-y, m/d/y, yyyymmdd, dd-Mon-yy or 7 digit julian date
echo.        If "%%date%%" is passed as the 2nd arg it will be interpreted
echo.        according to the current regional date setting ie. day dd/mm/yyyy
echo.        If /r is passed then the date contained in the DateEnv variable
echo.        and/or the [Date] argument will be interpreted in regional format
echo.        The /r option should be placed at the end of the list if used
echo.        The /r option should only be used if date input is not included
echo.        in one of the default listed formats or unexpected consequences...
echo.
echo.DateEnv, if passed alone may be a valid defined date variable or if
echo.undefined then todays date will be used to populate the variables
echo.Two digit years input 'XX' are interpreted as the year '20XX'
echo.Valid dates must be in the year 1601 or greater for the validity check
echo.Returns 0 in errorlevel if the date is valid, else non-zero
echo.
echo.If DateEnv is valid or if [Date] is passed DateEnv_??? will be set to:
echo.DateEnv_mdy will be set to mm-dd-yyyy
echo.DateEnv_ymd will be set to yyyymmdd
echo.DateEnv_y.m.d will be set to yyyy.mm.dd
echo.DateEnv_dte will be set to the current active regional date format
echo.DateEnv_jul will be set to the 7 digit Julian date
echo.DateEnv_dow will be set to day of week, ie. Monday, Tuesday, etc.
echo.DateEnv_vrb will be set to Verbose Date, ie. Saturday, August 20th, 2011
echo.DateEnv_dd will be set to the 2 digit day
echo.DateEnv_mm will be set to the 2 digit month
echo.DateEnv_yyyy will be set to the 4 digit year
echo.DateEnv_month will be set to the month, ie. February or December
echo.DateEnv_mon will be set to the 3 letter month, ie. Jan or Aug
echo.
echo.DateEnv itself will not be changed regardless if its a valid date or not
echo.Also formats yyyymmdd or 7 digit julian date input to desired output
echo.Example: Set_Date today "%%date%%" or Set_Date newyear99 01-Jan-99
echo.
echo.Finally:
echo.If DateEnv is not defined and there is no second argument then %%date%% in
echo.the current regional format will be used to populate the variables
echo.If /p is passed as 2nd argument then quoted 3rd argument will prompt for date
echo.
echo.Examples:
echo.         set "AprilsFools=4/1/1"
echo.         set_date AprilFools
echo.         echo Aprils fools date for 2001 in Julian format is: %%AprilFools_jul%%
echo.         echo Aprils fools date in 2001 was on a %AprilFools_dow% ^(Sunday^)
echo.         Set_Date birthday /p="Enter your birth date: "
echo.         ECHO You were born on a %%birthday_dow%%
echo.         set "today="
echo.         Set_Date today
echo.         echo today is %%today_dte%% or %%today_jul%% in Julian format
echo.
echo.If the '/p' option is used then the _GetString.cmd routine must be in the PATH
echo.         or else set/p routine will ask for date with no validity checking

Answer 9

下面有一个纯批处理解决方案，它只使用 DATE 命令和 %DATE% 变量，因此它适用于任何 Windows 版本。为了使这个程序真正通用，只需添加其他语言的 DATE 命令第二行显示的日期和月份部分的名称，并用斜杠括起来。例如，假设在德语中，日部分显示为 TT，因此您只需修改此值：set DayNames=/dd/tt/以便在德语 Windows 中也使用该程序（除了所有使用 DD 作为日部分的语言）。

@echo off
