How to rename multiple files with PowerShell

To rename multiple files using PowerShell, you can use the Rename-Item cmdlet. This cmdlet allows you to specify the path to the file or files you want to rename, and the new name for the file or files.

For example, suppose you have a directory with the following files:

To rename all of these files so that they have the extension .bak, you can use the following command:

This command uses the Get-ChildItem cmdlet to get a list of all files with the .txt extension, and pipes the results to the Rename-Item cmdlet. The -NewName parameter specifies the new name for the files, which is constructed by replacing the .txt extension with .bak.

You can also use the Rename-Item cmdlet to perform more complex renaming operations. For example, you can use regular expressions to match specific patterns in the filenames, and use backreferences to include parts of the original filename in the new name.

For more information about the Rename-Item cmdlet and how to use it, you can type Get-Help Rename-Item at the PowerShell prompt to read the documentation for the cmdlet.
