问题描述
我正在尝试使用Rename-Item
cmdlet执行以下操作:
I am trying to use the Rename-Item
cmdlet to do the following:
我有一个包含" *.txt "文件的文件夹.假设1.txt,2.txt等...
I have folder which contains "*.txt" files. Let's say 1.txt, 2.txt etc...
我想复制带有一些前缀的文件,将它们重命名为* .txt并覆盖所有现有文件(如果有的话).
I want to copy files that have some prefix, rename them to *.txt and override any existing files if there are any.
示例:
文件:1.txt,2.txt,3.txt,4.txt,5.txt,index.1.txt,index.2.txt,index.3.txt,index.4.txt,索引.5.txt
files : 1.txt, 2.txt, 3.txt, 4.txt, 5.txt, index.1.txt, index.2.txt, index.3.txt, index.4.txt, index.5.txt
我想使用重命名项过滤任何 index.*.txt
,并将它们重命名为 *.txt
,如果存在相同文件,请替换它.
I want to use rename-item to filter any index.*.txt
and rename them to *.txt
, and if the same file exists, replace it.
谢谢你们
推荐答案
如@lytledw所述,Move-Item -Force
非常适合重命名和覆盖文件.
As noted by @lytledw, Move-Item -Force
works great for renaming and overwriting files.
要替换名称的index.
部分,可以使用-replace
正则表达式运算符:
To replace the index.
part of the name, you can use the -replace
regex operator:
Get-ChildItem index.*.txt |ForEach-Object {
$NewName = $_.Name -replace "^(index\.)(.*)",'$2'
$Destination = Join-Path -Path $_.Directory.FullName -ChildPath $NewName
Move-Item -Path $_.FullName -Destination $Destination -Force
}
