替换部分文件名 Powershell

Question

I have files that are generated every morning:

• Default_20140227_05.00.29.csv
• Default_20140226_05.00.29.csv

I would like to rename the files:

• VOD_20140227_05.00.29.csv
• VOD_20140226_05.00.29.csv

I would basically be replacing Default with VOD .

I am using Powershell 1.0. Any help would be greatly appreciated.

Answer 1

简化：

ls *.csv | Rename-Item -NewName {$_.name -replace "Default","VOD"}

Answer 2

我没有要测试的 PowerShell 1.0，但假设您在文件所在的文件夹中运行它，您可以尝试：

Get-ChildItem Default_*.csv  |Rename-Item -NewName {$_.name -replace '^Default','VOD'}

Answer 3

gci | ?{$_.Name -like "Default*"} | % {$newname = ([String]$_).Replace("Default","VOD"); Rename-item $_ $newname}

A more explanatory version:

$DefaultFiles =  Get-ChildItem | Where-Object {$_.Name -like "Default*"}
ForEach($File in $DefaultFiles) 
{
    $newname = ([String]$File).Replace("Default","VOD")
    Rename-item -Path $File $newname
}

Answer 4

If you're looking for a generic version that will take your find and replace as parameters and log out what you've renamed (handy, imo), here's one building from Cole9350's answer :

$Find = $args[0]
$Replace = $args[1]
$TargetFiles =  Get-ChildItem | Where-Object {$_.Name -like "*$Find*"}
ForEach($File in $TargetFiles) 
{
    $newname = ([String]$File).Replace($Find,$Replace)
    write-host "Renaming $File to $newname"
    Rename-item -Path $File.PSPath $newname
}

And if you want it recursive, just add -Recurse after Get-ChildItem
