Windows批处理脚本:比较两个文件的创建日期 [英] Windows batch scripting: compare two files' created dates

问题描述

我想基于两个文件创建日期的比较来派生Windows批处理脚本，我不确定从哪里开始.我觉得一定有办法.有什么想法吗?

I would like to fork my Windows batch script based on a comparison of the created dates of two files, and I'm not sure where to begin. I feel like there must be a way. Any ideas?

更新: 在PA的答案中尝试了该解决方案.我将代码片段逐字复制到了当前脚本的末尾.然后，我在脚本的开头添加了此内容:

UPDATE: Tried the solution in PA's answer. I copied the code snippet verbatim to the end of my current script. Then, I added this early in the script:

IF EXIST "%PROGRAMFILES(X86)%" CALL :getCreationDate "%PROGRAMFILES(X86)%\oracle\jinitiator 1.3.1.28\lib\security\certdb.txt"

执行时给我一个错误: 无效的别名动词.

which gives me an error when I execute: Invalid alias verb.

推荐答案

您需要在等号前放一个脱字号以使其逃脱(cmd.exe太好了).我已经验证了此功能:

You need to put a caret before the equals sign to escape it (cmd.exe is sooo wonderful). I've verified this works:

setlocal enableextensions enabledelayedexpansion
call :getCreationDate "C:\Windows\Notepad.exe"
echo Creation Date is: %creationdate%
endlocal
goto :EOF
:getCreationDate
set FILE=%~f1
set FILE=%FILE:\=\\%
for /F "skip=1 tokens=* usebackq" %%A in (`wmic datafile where name^="%FILE%" get creationdate`) do (
    set creationdate=%%A
)
goto :EOF
