文件名中的批处理命令日期和时间 [英] Batch command date and time in file name

问题描述

我正在命令行上使用 WinZip 压缩文件.由于我们每天存档，因此我尝试为这些文件添加日期和时间，以便每次都自动生成一个新文件.

I am compressing files using WinZip on the command line. Since we archive on a daily basis, I am trying to add date and time to these files so that a new one is auto generated every time.

我使用以下来生成文件名.将其复制粘贴到命令行，您应该会看到一个带有日期和时间组件的文件名.

I use the following to generate a file name. Copy paste it to your command line and you should see a filename with a Date and Time component.

echo Archive_%date:~-4,4%%date:~-10,2%%date:~-7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.zip

输出

Archive_20111011_ 93609.zip

然而，我的问题是AM vs PM.AM 时间戳给了我时间 9(带有前导空格)与 10 自然占用两个空格的时间.

However, my issue is AM vs PM. The AM time stamp gives me time 9 (with a leading blank space) vs. 10 naturally taking up the two spaces.

我想我的问题也会扩展到前 9 天、前 9 个月等.

I guess my issue will extend to the first nine days, first 9 months, etc. as well.

如何解决这个问题，以便包含前导零而不是前导空格，以便获得 Archive_20111011_093609.zip?

How do I fix this so that leading zeroes are included instead of leading blank spaces so I get Archive_20111011_093609.zip?

推荐答案

另一种解决方案:

for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set datetime=%%I

它会给你(独立于区域设置！):

It will give you (independent of locale settings!):

  20130802203023.304000+120
( YYYYMMDDhhmmss.<milliseconds><always 000>+/-<minutes difference to UTC>  )

从这里开始，很容易:

set datetime=%datetime:~0,8%-%datetime:~8,6%
20130802-203023

对于 Logan 对文件的修改日期时间"的相同输出格式的请求:

For Logan's request for the same outputformat for the "date-time modified" of a file:

for %%F in (test.txt) do set file=%%~fF
for /f "tokens=2 delims==" %%I in ('wmic datafile where name^="%file:=\%" get lastmodified /format:list') do set datetime=%%I
echo %datetime%

它有点复杂，因为它只适用于完整路径，wmic 期望反斜杠加倍并且 = 必须被转义(第一个. 第二个由周围的引号保护).

It is a bit more complicated, because it works only with full paths, wmic expects the backslashes to be doubled and the = has to be escaped (the first one. The second one is protected by surrounding quotes).
