创建一个文件名作为批处理作业时间戳 [英] Creating a file name as a timestamp in a batch job
问题描述
我们有运行每天将文件复制到一个文件夹皮卡批处理作业。我也想采取文件的副本,并将其与文件名拖放到存档文件夹
YYYY-MM-dd.log
什么是在Windows批处理作业要做到这一点最简单的方法?
基本上,我找这Unix命令的等效:
CP source.log`日期+%F`.log
CP source.log%DATE:〜-4% - %DATE:〜4.2% - %DATE: 〜7.2%.LOG
但它的环境相关。我不知道,如果%DATE%
是局部的,或者依赖于在Windows短日期指定的格式。
下面是一个语言环境无关的方式来提取这个答案当前日期,但是它取决于 WMIC
和 FOR / F
:
FOR / F %% A IN('WMIC OS GET LocalDateTime ^ |。FINDSTR \\')DO @SET B = %%一
CP source.log%B:〜0,4% - %B:〜4.2% - %B:〜6,2%.LOG
We have a batch job that runs every day and copies a file to a pickup folder. I want to also take a copy of that file and drop it into an archive folder with the filename
yyyy-MM-dd.log
What's the easiest way to do this in a Windows batch job?
I'm basically looking for an equivalent of this Unix command:
cp source.log `date +%F`.log
CP source.log %DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%.log
But it's locale dependent. I'm not sure if %DATE%
is localized, or depends on the format specified for the short date in Windows.
Here is a locale-independent way to extract the current date from this answer, but it depends on WMIC
and FOR /F
:
FOR /F %%A IN ('WMIC OS GET LocalDateTime ^| FINDSTR \.') DO @SET B=%%A
CP source.log %B:~0,4%-%B:~4,2%-%B:~6,2%.log
