Pattern matching in powershell to rename folder - powershell

Question

I am trying to script to rename username folders, but some of the folders are named USERNAME_S11-121-121.... I want to verify path using test-path with wild cards and rename-item doesn't take wild cards.
Is there a way I can use test-path and rename-item with just username and exclude everything except username.
I don't know if test-path $path* is correct way of doing it?
Function Reset-Profile {
param(
[parameter(Mandatory = $true, Position = 0)]
[string] $UserName,
[parameter(Mandatory = $true, Position = 1, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true)]
$Server
)
process{
$SelectedUser = $UserName
$randomNumber = Get-Random
Foreach($UserName in $Server){
$paths = #(
"\\$Server\c$\users\$SelectedUser" #local profile
"\\server01\users$\$SelectedUser", #roaming profile
"\\server02\usersupmprd$\$SelectedUser" #roaming profile
)
foreach ($path in $paths)
{
if(test-path $path or test-path $path*)
{
Rename-Item -path $path -NewName "$SelectedUser.$randomNumber"
break;
write-host profile renamed under $path to
$SelectedUser.$randomNumber
}
else{ write-host path not found}
}
}
}
}

Untested, but try this:
Function Reset-Profile {
[cmdletbinding()]
param(
[parameter(Mandatory = $true, Position = 0)]
[string] $UserName,
[parameter(Mandatory = $true, Position = 1, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true)]
[string[]] $Server
)
Process{
$randomNumber = Get-Random
ForEach($Host in $Server)
{
$paths = #("\\$Host\c$\users\$UserName", #local profile
"\\server01\users$\$UserName", #roaming profile
"\\server02\usersupmprd$\$UserName") #roaming profile
ForEach ($path in $paths)
{
if(test-path "$path")
{
$CurrentPath = Get-Item "$path"
}
elseif(test-path $path_*)
{
write-host $path
$CurrentPath = Get-Item "$($path)_*" #it's necessary to put $path_ in parenthesis otherwise it conflicts with some internal command and gets the path of the directory I am working in.
write-host $CurrentPath
}
else {
Write-Warning "Path not found"
}
if($CurrentPath.Count() -eq 1)
{
Rename-Item -Path $CurrentPath -NewName "$UserName.$randomNumber"
Write-Verbose "Profile renamed under $path to $UserName.$randomNumber"
} elseif ($CurrentPath.Count -gt 1) {
Write-Warning "Multiple matches for $path"
} else {
Write-Warning "Path $path not found"
}
}
}
}
}
Explanation:
Added [string[]] in front of $Server so that it explicitly accepts array input (as well as a single string).
Changed ForEach($Username in $Server) to ForEach($Host in $Server) and made use of $Host so that it loops through the servers correctly.
Uses Get-ChildItem $Path* to get any matching paths. Then checks if a single path has been returned, if it has then it will do the rename, if it's multiple
or if there was no match it will warn you as such.
Changed write-host to write-verbose which will require use of the -verbose switch to be seen. Write-host is an anti-pattern, particularly in a Function.
How to execute:
I suggest you run this as follows initially (because i've added [cmdletbinding()] at the top of your function it now supports -WhatIf and -Verbose which should pass in to the Rename-Item cmdlet and will show you what it does. If it looks right, simply remove -WhatIf:
Reset-Profile -Username TestUsername -Server Localhost -WhatIf -Verbose
