Question

我使用以下格式的日期列输入数据：

MM/DD/YYYY H:M:S

我正在尝试将其更改为：

YYYY/MM/DD H:M:S

如果可能，我想在.bat文件中执行此操作。

编辑，这是Endoro的答案：

set "mydate=MM/DD/YYYY H:M:S"

for /f "tokens=1-4 delims=/ " %%i in (txt) do (

set "month=%%i"
set "day=%%j"
set "year=%%k"
set "mytime=%%l"

) set "newtime=%year%/%month%/%day% %mytime%"

echo %newtime%

让我添加我想在逗号分隔的文本文件中执行此操作，如果这有帮助。

编辑：前两行文件：

05/20/2013 11:00:28,1,048392,3.17,98%,4.8,13.3,50.7,29.2,29.9,29.2,2

05/20/2013 12:00:22,1,048392,3.17,98%,4.8,13.3,50.4,31.6,36,31.4,3

Answer 1

您还可以使用for /f循环：

@echo off&setlocal
set "mydate=MM/DD/YYYY H:M:S"
for /f "tokens=1-4 delims=/ " %%i in ("%mydate%") do (
    set "month=%%i"
    set "day=%%j"
    set "year=%%k"
    set "mytime=%%l"
)
set "newtime=%year%/%month%/%day% %mytime%"
echo %newtime%

..输出是：

YYYY/MM/DD H:M:S

Answer 2

set "dat1=MM/DD/YYYY h:m:s"
set "dat2=%dat1:~6,4%/%dat1:~0,3%%dat1:~3,2%%dat1:~10%"
echo %dat1% - %dat2%

Answer 3

试试这个 - 基于Endoro的代码和您提供的额外信息。

@echo off
for /f "tokens=1,2,3,* delims=/ " %%i in ('type "file.csv"') do (
echo %%k/%%i/%%j %%l
)>"newfile.csv"

Windows批处理（.bat）命令用于修改列的日期格式
