batch rename using windows powershell
Mohammed Ismail
I am busy with a windows powershell script to batch rename a bunch of folders with IDs, which works perfectly fine. My question is how do i add validation to ensure all the IDs are unique when all my files get renamed. Here is the code:
param(
[Parameter(Mandatory=$true)]
[int]$idx
)
Get-ChildItem *.sql | Foreach-Object {
$iPrefix = ('{0:d5}' -f $idx)
$path = (Split-Path -Path($_))
$filename = (Split-Path -Path($_) -Leaf) -replace "\[|\]",""
#%{ write-host $path}
%{ write-host $filename}
if(!$filename.StartsWith("script","CurrentCultureIgnoreCase"))
{
#%{ write-host "Script$iPrefix - $filename"}
Rename-Item -LiteralPath(($_)) -NewName("Script$iPrefix - $filename")
++$idx
%{ write-host "Renamed: " + $filename}
}
}
Here is a screenshot of what i want to avoid: 
As you can see Script02185 is repeated twice, because the script was ran at two different times. How do i ensure that the numbers will remain unique?

Try this.
$files = Get-ChildItem . -Filter *.sql
$prefixedFiles, $unprefixedFiles = $files.Where({ $_.Name -match "^Script\d{5} - " }, 'split')
$usedIDs = [int[]]$prefixedFiles.Name.Substring(6, 5)
$unusedIDs = [System.Collections.Generic.HashSet[int]](1..99999)
$unusedIDs.ExceptWith($usedIDs)
$enumerator = $unusedIDs.GetEnumerator()
$unprefixedFiles | Rename-Item -NewName {
if (!$enumerator.MoveNext()) { throw "`nThere are no unused IDs." }
"Script{0:D5} - {1}" -f $enumerator.Current, ($_.Name -replace '\[|\]')
} -ErrorAction Stop -PassThru
