在 PowerShell 中重命名许多文件夹
我有超过 1000 个文件需要重命名。
第一组文件夹和/或文件按位置分组，因此每个文件的前四个字符相同；有四到五个不同的地点。我需要删除文件夹名称的前几个字符。
例子：
旧文件：ABC_Doe，Jane
新文件：Doe，Jane
对于执行此操作的最快方法有什么建议吗？
我已尝试以下所有方法：
1st Attempt
$a = Get-ChildItem C:\example
$b = Where-Object {$_.name -like “*ABC_*”}
$cmdlet_name = “Rename-Item”
$d = (cmdlet_name $a $b)
invoke-expression $d
2nd Attempt
$e = Get-ChildItem C:\example
$f = $e.TrimStart (“ABC_”)
第三次尝试
Rename-Item -{$_.name -like “*ASD*”, “”}
I have over 1000+ files that have to be renamed.
The first set folder and/or files are grouped by location, so the first four characters are the same for each file; there are four-five different locations. I need to delete the first few characters of the folder's name.
Example:
Old File: ABC_Doe, Jane
New File: Doe, Jane
any suggestions as to the quickest way to carry this out?
I've tried all of the following:
1st Attempt
$a = Get-ChildItem C:\example
$b = Where-Object {$_.name -like “*ABC_*”}
$cmdlet_name = “Rename-Item”
$d = (cmdlet_name $a $b)
invoke-expression $d
2nd Attempt
$e = Get-ChildItem C:\example
$f = $e.TrimStart (“ABC_”)
3rd Attempt
Rename-Item -{$_.name -like “*ASD*”, “”}

试试这个，获取所有子项目（仅文件），通过替换它们（什么都不做）来删除 abc_ 并重命名每个文件。要重命名子目录中的文件，请将 -Recurse 开关添加到 Get-ChildItem 命令：
UPDATE
实际上，这应该也可以工作并且要短得多（不需要附加文件扩展名，因为执行了重命名关于文件名）。
Try this, get all child items (files only), remove abc_ by replacing them (with nothing) and rename each file. To rename files in sub-directories add the -Recurse switch to the Get-ChildItem command:
UPDATE
Actually, this should work as well and is much shorter (no need to append the file extension cause renaming is performed on the file name).
