Replace Part of File Name 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

simplified:

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

Answer 2

I do not have PowerShell 1.0 to test, but assuming you are running this in the folder where files reside, you can try:

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