PowerShell - Renaming a bunch of folders

In my previous post I talked about Organizing my script directory, naming convention, preferences and bottlenecks... Today let's reorganize some of those script folders.

Renaming a bunch of folders

At my work, all the scripts related to VMware are named ESX-<Category>-<Explicit Title>. And I use the same naming convention at home for my own scripts. So let's say I want to rename all those *ESX* folders by VMWARE instead.
Something like this: VMWARE-<Category>-<Explicit Title>



First, we start by listing the directories which contain "ESX"

PS C:\LazyWinAdmin\POSH> Get-ChildItem -Path *ESX* -Directory

    Directory: C:\LazyWinAdmin\POSH


Mode                LastWriteTime     Length Name
----                -------------     ------ ----
da---        2013-10-22   9:05 PM            ESX-DATASTORE-MultiPathing_Enforce
da---        2013-10-22   9:05 PM            ESX-HOST-AutoDeploy
da---        2013-10-22   9:04 PM            ESX-HOST-Resources_Report
da---        2013-10-22   9:05 PM            ESX-NETWORK-Migrate_VM
da---        2013-10-22   9:05 PM            ESX-VM-Information_Report
da---        2013-10-22   9:05 PM            ESX-VM-Snapshot_Report
da---        2013-10-22   9:04 PM            FUNCT-ESX-VM-Disable-CopyPaste
da---        2013-10-22   9:04 PM            FUNCT-ESX-VM-Enable-CopyPaste

We take a look at the Help of Rename-Item using ShowWindow, just to make sure we type the right parameters.

PS C:\LazyWinAdmin\POSH> Get-Help -Name Rename-Item -ShowWindow

We will need to use the Path and the NewName parameters to specify the current name(path) and the new name. I end up with the following line, let's try it using WhatIf switch

PS C:\LazyWinAdmin\POSH> Get-ChildItem -Path *ESX* -Directory | ForEach-Object -Process {Rename-item -Path $_.Name -NewName ($_.name -replace "ESX","VMWARE") -WhatIf}

This line can be translated to: Get me all the folder that contains

What if: Performing the operation "Rename Directory" on target "Item: C:\LazyWinAdmin\POSH\ESX-DATAS
TORE-MultiPathing_Enforce Destination: C:\LazyWinAdmin\POSH\VMWARE-DATASTORE-MultiPathing_Enforce".

Looks Good to me :-) ! let's try using Verbose!

PS C:\LazyWinAdmin\POSH> Get-ChildItem -Path *ESX* -Directory | ForEach-Object -Process {Rename-item
-Path $_.Name -NewName ($_.name -replace "ESX","VMWARE") -Verbose}
