Hi Megan,


Here's a sample to rename all files in c:\scripts directory, remove -whatIf
when you are ready to perform the rename:


# three files in c:\scripts

PS > dir c:\scripts

Mode LastWriteTime Length Name
---- ------------- ------ ----
-a--- 7/11/2008 13:33:10 0.0 B file1.txt
-a--- 7/11/2008 13:33:10 0.0 B file2.txt
-a--- 7/11/2008 13:33:10 0.0 B file3.txt


# get all files in c:\scripts, exclude directories, rename each file to 'parentDirectoryName_fileName.ext'

PS> dir c:\scripts | where {!$_.PSIsContainer} | rename-item -newName {$_.directory.name+"_"+$_.name}
-whatIf

What if: Performing operation "Rename File" on Target "Item: C:\scripts\file1.txt
Destination: C:\scripts\scripts_file1.txt".
What if: Performing operation "Rename File" on Target "Item: C:\scripts\file2.txt
Destination: C:\scripts\scripts_file2.txt".
What if: Performing operation "Rename File" on Target "Item: C:\scripts\file3.txt
Destination: C:\scripts\scripts_file3.txt".
