【Window Power Shell】用powershell修改文檔/文件夾創建時間、修改時間

用win7自帶的powershell可以輕松修改文檔/文件夾創建時間、修改時間。而且可以批量修改。

1. 步驟

新建一個bat文件，在其中添加語句：

@ECHO OFF
powershell.exe -command "ls 'folder_path\*.dll' | foreach-object { $_.LastWriteTime = Get-Date; $_.CreationTime = Get-Date }"
PAUSE

2. 解釋

代碼將folder_path路徑下的所有dll文件的創建時間和修改時間改成現在的時間。

-command: tells powershell to run the following command and return immediately

ls: list all matching files at the path specified

foreach-object: run the following block on each file that ls found

$_.LastWriteTime = Get-Date: for each file, set the LastWriteTime to the value returned by Get-Date (today’s date and time)

$_.CreationTime = Get-Date： for each file, set the CreationTime to the value returned by Get-Date (today’s date and time)

3.修改至指定時間

將$_.LastWriteTime = Get-Date:改為$_.LastWriteTime = '01/11/2004 22:13:36'：

@ECHO OFF
powershell.exe -command "ls 'folder_path\*.*' | foreach-object { $_.LastWriteTime = '01/11/2004 22:13:36'; $_.CreationTime = '01/11/2004 22:13:36' }"
PAUSE

4. 遞歸文件夾中所有文件

@ECHO OFF
powershell.exe -command "Get-Childitem -path 'E:\project_llj\install\test\' -Recurse | foreach-object { $_.LastWriteTime = Get-Date; $_.CreationTime = Get-Date }" 
PAUSE
