windows10用powershell修改文档/文件夹创建时间、修改时间、访问时间

参考博文:windows用powershell修改文档/文件夹创建时间、修改时间

用win10自带的powershell可以轻松修改文档/文件夹创建时间、修改时间。而且可以批量修改。

1. 步骤:

  新建一个bat文件,在其中添加语句:

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

 

2. 解释:

  代码将folder_path路径下的所有dll文件的创建时间和修改时间改成现在的时间。

  -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. 修改至指定时间:

  将$_.LastWriteTime = Get-Date:改为$_.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. 递归文件夹中所有文件:

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

5. 递增变量设置函数接口:

AddYears、AddMonths、AddDays、AddHours、AddMinutes、AddSeconds、AddMilliseconds、AddTicks
