如何在Windows命令行上获取当前的日期时间，以适合的格式使用文件名？ [英] How to get current datetime on Windows command line, in a suitable format for using in a filename?

问题描述

编辑：现在是2016年，我将使用powershell，除非有一个非常引人注目的向后兼容的原因，特别是因为使用的区域设置问题日期。请参阅@ npocmaka的 http://stackoverflow.com/a/19799236/8479

什么是Windows命令行语句我可以使用哪种格式获取当前的日期时间，可以放入文件名？

我想拥有一个.bat文件，将目录作为名称的一部分将当前日期和时间的目录卷入归档，例如 Code_2008-10- 14_2257.zip 。有没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？

我不太了解日期格式，最好是yyyy-mm-dd，但任何简单的都很好。

到目前为止，我已经得到了，在我的机器上给了我 Tue_10_14_2008_230050_91 ：

  rem以可以进入文件名的格式获取日期时间。 
 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现在使用新的ZIP文件名中的时间戳。 
d：\Program Files\7-Zip\7z.exea -r代码_％_ my_datetime％.zip代码
  

我可以这样生活，但似乎有点笨重。理想情况下，它会更加简洁，并具有前面提到的格式。

我使用的是Windows Server 2003和Windows XP专业版。我不想安装额外的实用程序来实现这一点（尽管我意识到有些会做出很好的日期格式化）。

解决方案

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

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

如果您喜欢24小时/军事格式的时间，您可以用以下替换第二个FOR行： p>

 对于/ ftokens = 1-2 delims = /：%% a in（％TIME％）do mytime = %% a %% b）
  

C：>。 \\ date.bat

2008-10-14_0642

如果你想要他独立于区域日/月订单，可以使用WMIC os GET LocalDateTime作为源，因为它是ISO顺序：

  @echo off 
 for / Fusebackq tokens = 1,2 delims ==%% i in（`wmic os get LocalDateTime / VALUE 2 ^&Nine`）如果'。%% 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本地日期是[％ldt％] 
  / pre> 
 
 
 
 
 C：> test.cmd 
 
本地日期是[2012-06-19 10:23 ：47.048] 
 
 
 编辑：添加了您问题中最初要求的时间以及日期b $ b 编辑：使用WMIC添加与区域无关的变体
 
EDIT: Now that it's 2016 I'd use powershell for this unless there's a really compelling backwards-compatible reason for it, particularly because of the regional settings issue with using date. See @npocmaka's http://stackoverflow.com/a/19799236/8479



What's a Windows command line statement(s) I can use to get the current datetime in a format that I can put into a filename?

I want to have a .bat file that zips up a directory into an archive with the current date and time as part of the name, for example, Code_2008-10-14_2257.zip. Is there any easy way I can do this, independent of the regional settings of the machine?

I don't really mind about the date format, ideally it'd be yyyy-mm-dd, but anything simple is fine.

So far I've got this, which on my machine gives me 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
I can live with this, but it seems a bit clunky. Ideally it'd be briefer and have the format mentioned earlier.

I'm using Windows Server 2003 and Windows XP Professional. I don't want to install additional utilities to achieve this (although I realise there are some that will do nice date formatting).
解决方案
See Windows Batch File (.bat) to get current date in MMDDYYYY format.:
@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%
If you prefer the time in 24hr/military format, you can replace the second FOR line with this: 
For /f "tokens=1-2 delims=/:" %%a in ("%TIME%") do (set mytime=%%a%%b)



  
C:> .\date.bat 

  2008-10-14_0642
If you want the date independently of the region day/month order, you can use "WMIC os GET LocalDateTime" as a source, since it's in ISO order:
@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

  Local date is [2012-06-19 10:23:47.048]
EDIT: Added the time as well as the date as originally requested in your question
EDIT: Added a region-independent variation using WMIC
