Как добавить дату в пакетных файлах

Question

У меня есть следующая строка в командном файле (которая работает на старом Windows 2000 поле):

7z a QuickBackup.zip *.backup

Как добавить дату в файл QuickBackup.zip. Поэтому, если бы я запускал пакетный файл сегодня, в идеале, файл будет QuickBackup20090514.zip.

Есть ли способ сделать это?

Answer 1

Существует технический рецепт здесь , который показывает, как отформатировать его в MMDDYYYY, вы должны быть в состоянии адаптировать его для своих нужд.

echo on
@REM Seamonkey’s quick date batch (MMDDYYYY format)
@REM Setups %date variable
@REM First parses month, day, and year into mm , dd, yyyy formats and then combines to be MMDDYYYY
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%

echo %date%

РЕДАКТИРОВАТЬ: причина не работала раньше была из-за «умные цитаты» в оригинальном тексте. Я исправил их, и пакетный файл будет работать, если вырезать и вставить с этой страницы.

Я использовал технику переменных среды, описанную здесь: http://cwashington.netreach.net/depo/view.asp?Index=19

::  Description  :  Sets or clears a group of environment variables containing

::  Requires     :  Windows NT with command extensions enabled

::  USAGE
::
::  SetEnvDate1 can be used as a model for coding date/time routines in
::  other scripts, or can be used by itself as a utility that is called
::  from other scripts.
::  
::  Run or call SetEnvDate1 without arguments to set the date variables.
::  Variables are set for the day abbreviation (DT_DAY), month number (DT_MM),
::  day number (DT_DD) and four-digit year (DT_YYYY).
::
::  When the variables are no longer needed, clean up the environment by
::  calling the script again with the CLEAR argument.  E.g.,
::
::       call SetEnvDate1 clear
::-----------------------------------------------------------------------------
::  NOTES
::
::  A time variable could be added by parsing the string returned by the
::  built-in TIME /T command.  This is left as an exercise for the reader. B-)
::
::  This script illustrates the following NT command extensions:
::
::  1.  Use of the extended IF command to do case-insensitive comparisons.
::
::  2.  Use of the extended DATE command.
::
::  3.  Use of the extended FOR command to parse a string returned by a
::      command or program.
::
::  4.  Use of the "()" conditional processing symbols to group commands
::      for conditional execution.  All commands between the parens will
::      be executed if the preceeding IF or FOR statement is TRUE.
::-----------------------------------------------------------------------------

if not "%1" == "?" goto chkarg
echo.
echo Sets or clears date/time variables in the command environment.
echo.
echo    SetEnvDate1 [clear]
echo.
echo When called without arguments, the variables are created or updated.
echo When called with the CLEAR argument, the variables are deleted.

Основываясь на идее Джо, вот версия, которая будет создавать свой собственный (.js) помощник и время поддержки:

@echo off

set _TMP=%TEMP%\_datetime.tmp

echo var date = new Date(), string, tmp;> "%_TMP%"
echo tmp = ^"000^" + date.getFullYear(); string = tmp.substr(tmp.length - 4);>> "%_TMP%"
echo tmp = ^"0^" + (date.getMonth() + 1); string += tmp.substr(tmp.length - 2);>> "%_TMP%"
echo tmp = ^"0^" + date.getDate(); string += tmp.substr(tmp.length - 2);>> "%_TMP%"
echo tmp = ^"0^" + date.getHours(); string += tmp.substr(tmp.length - 2);>> "%_TMP%"
echo tmp = ^"0^" + date.getMinutes(); string += tmp.substr(tmp.length - 2);>> "%_TMP%"
echo tmp = ^"0^" + date.getSeconds(); string += tmp.substr(tmp.length - 2);>> "%_TMP%"
echo WScript.Echo(string);>> "%_TMP%"

for /f %%i in ('cscript //nologo /e:jscript "%_TMP%"') do set _DATETIME=%%i

del "%_TMP%"

echo YYYYMMDDhhmmss: %_DATETIME%
echo YYYY: %_DATETIME:~0,4%
echo YYYYMM: %_DATETIME:~0,6%
echo YYYYMMDD: %_DATETIME:~0,8%
echo hhmm: %_DATETIME:~8,4%
echo hhmmss: %_DATETIME:~8,6%

Answer 4

Я нашел два способа, которые работают независимо от настроек даты.

На моем ПК дата / т возвращается 2009-05-27

Вы можете получить доступ к реестру и прочитать региональные настройки (HKEY_CURRENT_USER \ Панель управления \ Международная)

Или используйте VBScript. Это некрасивый гибрид пакетного файла / vbscript, который я создал некоторое время назад ....

@Echo Off
set rnd=%Random%
set randfilename=x%rnd%.vbs

::create temp vbscript file
Echo Dim DayofWeek(7) >  %temp%\%randfilename%
Echo DayofWeek(1)="Sun" >> %temp%\%randfilename%
Echo DayofWeek(2)="Mon" >> %temp%\%randfilename%
Echo DayofWeek(3)="Tue" >> %temp%\%randfilename%
Echo DayofWeek(4)="Wed" >> %temp%\%randfilename%
Echo DayofWeek(5)="Thu" >> %temp%\%randfilename%
Echo DayofWeek(6)="Fri" >> %temp%\%randfilename%
Echo DayofWeek(7)="Sat" >> %temp%\%randfilename%
Echo DayofWeek(0)=DayofWeek(Weekday(now)) >> %temp%\%randfilename%
Echo Mon=Left(MonthName(Month(now),1),3) >> %temp%\%randfilename%
Echo MonNumeric=right ( "00" ^& Month(now) , 2) >> %temp%\%randfilename%
Echo wscript.echo ( Year(Now) ^& " " ^& MonNumeric ^& " " ^& Mon ^& " "  _ >> %temp%\%randfilename%
Echo ^& right("00" ^& Day(now),2) ^& " "^& dayofweek(0) ^& " "^& _ >> %temp%\%randfilename%
Echo right("00" ^& Hour(now),2)) _ >> %temp%\%randfilename%
Echo ^&":"^& Right("00" ^& Minute(now),2) ^&":"^& Right("00" ^& Second(Now),2)  >> %temp%\%randfilename%

::set the output into vars
if "%1" == "" FOR /f "usebackq tokens=1,2,3,4,5,6" %%A in (`start /wait /b cscript //nologo %temp%\%randfilename%`) do Set Y2KYear=%%A& Set MonthNumeric=%%B& Set Month=%%C& Set Day=%%D& Set DayofWeek=%%E& Set Time=%%F
set year=%y2kyear:~2,2%

::cleanup
del %temp%\%randfilename%

Это не красиво, но работает.
