Rename multiple files in a directory / Replace part of a filename in multiple files

Hi All,

This morning I was generating some scripts out of SSMS and it had some wired names attached to it. I wanted to rename them all manually, then it occured that if I write a Powershell script, I could reuse this code for something else in future.. So, here it goes:

Running the script :

PowerShell

[If you get errors, use Set-ExecutionPolicy cmdlet to set the correct permissions]

#Script to remove / rename part of filenames on multiple files..

 

$a = $args.length

if($a -eq 3)

{

$workingfolder = $args[0];

$pattern = $args[1];

$replacetext = $args[2];

}

else

{

write-warning "No. or arguments invalid. Usage: "

break;

}

function Recurse([string]$path) {

$fc = new-object -com scripting.filesystemobject

$folder = $fc.getfolder($path)

foreach ($i in $folder.files) {

$path=$i | select Path

$path = $path -replace "@{Path=",""

$path = $path -replace "}",""

$name=$i | select Name

$name=$name -replace "@{Name=",""

$name=$name -replace "}",""

$name=$name -replace $pattern,$replacetext

Write-Host Renaming $path to $name

#Write-Host $name

Rename-Item $path $name

}

foreach ($i in $folder.subfolders) {

Recurse($i.path)

}

}

Recurse($workingfolder);
