Rename-Item
Description
Change the name of an existing item
Usage
Options
Example(s)
Rename a file:
PS C:\>rename-item -path c:\docs\dump.csv -newname Report.xls
Rename all .TXT files as .LOG files in the current directory:
PS C:\>get-childitem -Path *.txt | rename-item -NewName {$_.name -replace".txt",".log"}
Because the -Newname parameter does not accept wildcards, the above works by piping the output of Get-ChildItem and then using a -replace expression to calculate all the new filenames.
