如何批量获取文件的与语言环境无关的修改时间和创建时间?

问题描述

与批量变量/参数扩展类似%~t1 可以获取文件的时间戳.

With batch variable/parameter expansion like %~t1 one can get a timestamp of a file.

我想将文件的年份设置为另一个变量想支持多个语言环境.

I would like to set the year of the file to another variable would like to support multiple locales.

如何获得文件的日期时间，而不受语言环境和区域设置的影响?请不要使用powershell.

How can you get a file's datetime, independent of locale and regional settings? No powershell please.

推荐答案

我会发布几个选项

1)第一个是 wmic(不适用于 XP 家庭版)(LastModified 可以用 CreationDate 或 LastAccessed )

1)First one is with wmic (not available for XP home edition) (LastModified can be changed with CreationDate or LastAccessed )

@echo off

set file_loc=.	emp_file
for %%# in ("%file_loc%") do set file_loc=%%~dpfnx#
set file_loc=%file_loc:=\%


for /f "delims=." %%t in ('"WMIC DATAFILE WHERE name="%file_loc%" get LastModified /format:value"') do (
    for /f %%$ in ("%%t") do if "%%$" neq "" set %%$
)

echo %LastModified%
echo year : %LastModified:~0,4%
echo month : %LastModified:~4,2%
echo day : %LastModified:~6,2%

2).Jscript/.bat hybrid (DateLastModified 可以改成 DateCreated 或 DateLastAccessed 时间格式可以随便改你想要):

2). Jscript/.bat hybrid (DateLastModified can be changed to DateCreated or DateLastAccessed .Time format can be changed to whatever you want ):

@if (@X)==(@Y) @end /****** jscript comment ******
@echo off

set file_loc=.	emp_file
for %%# in ("%file_loc%") do set file_loc=%%~dpfnx#
::set file_loc=%file_loc:=\%
cscript //E:JScript //nologo "%~f0" "%file_loc%"
exit /b 0

****** end of jscript comment ******/

var file_loc = WScript.Arguments.Item(0);
var fso = new ActiveXObject("Scripting.FileSystemObject");
var the_file=fso.GetFile(file_loc);
var the_date= new Date(the_file.DateLastModified);
WScript.Echo(the_date.getFullYear());
WScript.Echo(the_date.getMonth());
WScript.Echo(the_date.getUTCDate());

3) selfcompiled jscript.net/bat hybrid(GetLastWriteTime可以改为GetLastAccessTime或GetCreationTime.时间格式可以更改):

3) selfcompiled jscript.net/bat hybrid (GetLastWriteTime can be changed to GetLastAccessTime or GetCreationTime . Time format can be changed) :

@if (@X)==(@Y) @end /****** silent line that start jscript comment ******

@echo off
::::::::::::::::::::::::::::::::::::
:::       compile the script    ::::
::::::::::::::::::::::::::::::::::::
setlocal
if exist "%~n0.exe" goto :skip_compilation

set "frm=%SystemRoot%Microsoft.NETFramework"
:: searching the latest installed .net framework
for /f "tokens=* delims=" %%v in ('dir /b /s /a:d /o:-n "%SystemRoot%Microsoft.NETFrameworkv*"') do (
    if exist "%%vjsc.exe" (
        rem :: the javascript.net compiler
        set "jsc=%%~dpsnfxvjsc.exe"
        goto :break_loop
    )
)
echo jsc.exe not found && exit /b 0
:break_loop


call %jsc% /nologo /out:"%~n0.exe" "%~dpsfnx0"
::::::::::::::::::::::::::::::::::::
:::       end of compilation    ::::
::::::::::::::::::::::::::::::::::::
:skip_compilation



set file_loc=.	emp_file
for %%# in ("%file_loc%") do set file_loc=%%~dpfnx#


"%~n0.exe" "%file_loc%"


exit /b 0


****** end of jscript comment ******/
import System;
import System.IO;

var arguments:String[] = Environment.GetCommandLineArgs();

var the_file=arguments[1];
var last_modified=File.GetLastWriteTime(the_file);
 Console.WriteLine(last_modified.ToString("yyyy-MM-dd"));

4).robocopy - 使用它您只能获得最后修改日期(使用其他方法可以获得所有时间属性).因为 robocopy 中的时间戳始终是 YYYY/MM/DD HH:mm:SS 这个可以用...

4). robocopy - with this you can get only last modified date (with other methods you can get all time attributes).As time stamps in robocopy are always YYYY/MM/DD HH:mm:SS this can be used...

@ECHO OFF

set file_loc=.	emp_file
for %%# in ("%file_loc%") do set file_dir=%%~dp#
for %%# in ("%file_loc%") do set file_name=%%~nx#
pushd %file_dir%

for /f "tokens=1,2" %%a in ('robocopy  "." "%temp%" /l /fat /ts /LEV:1 /NP /NC /NS /NJS /NJH^|findstr /i /e /c:"%file_name%"') do (
    echo %%a %%b
)
popd

编辑这里准备好使用所有列出的方法使用参数化脚本:

EDIT Here are ready to use parametrized scripts using all the listed methods:

1. fileModifiedTime.bat - 获取最后修改时间具有设置独立格式的文件.基于 robocopy
2. fileTimes.bat - 获取文件时间戳使用 WMIC
3. dirTimes.bat - 获取目录时间戳使用 WMIC
4. fileTimesJS.bat - 文件时间jscript
标记
5. dirTimesJS.bat - 目录时间jscript
标记
6. fileTimesNET.bat - 文件.NET
的时间戳
7. dirTimesNET.bat - 目录.NET
的时间戳

1. fileModifiedTime.bat - gets last modified time of file with settings independent format.Based on robocopy
2. fileTimes.bat - gets file time stamps with WMIC
3. dirTimes.bat - gets directory time stamps with WMIC
4. fileTimesJS.bat - file time stamps with jscript
5. dirTimesJS.bat - directory time stamps with jscript
6. fileTimesNET.bat - file time stamps with .NET
7. dirTimesNET.bat - dir time stamps with .NET
