The second foo is replaced with bar, which is not what you want.
For example, if you had a file named “foofoo.jpg”, then the corresponding command generated by the above code would be: The second is that since sed replaces the second instance of foo in a line, it does not handle the case where the file name had multiple instances of foo in the first place. The awk command prints the first field $1 in each line of input, and the spaces in the file name causes the first word of the filename to be treated as the entire first field. The first is that since it does not work with file names with spaces. As with the main batch rename technique, you could pipe the output to /bin/bash but this is not recommended.
Until then, peace.Finally, the entire output is saved to rename.txt for user review to ensure that the rename commands are being generated correctly.

Thanks again, Matt, for sharing your time and knowledge. I always enjoy helping fellow employees find ways to be more efficient and save time and money. Imagine how much “fun” it would be to rename all of these files manually or with some clunky old batch file. Cristofer said he will probably need to use these commands for renaming 1000+ files in the near future, and he will share this process with other members of his team.
It is always fun to solve business challenges with Windows PowerShell commands. Note the location and file name of the transcript file, and open this file to see the results.After the command completes, run Stop-Transcript.Run your command (including the -WhatIf parameter).If you need a log file that shows the results of using -WhatIf, you can follow these steps:
Navigate to the directory containing the files to rename using the ' cd ' command ('cd' stands for. You can also type ' cmd ' and press Enter in the Windows Start Menu text field.

In order to batch rename file extensions, you will first need to open the Windows Command Prompt. Get-ChildItem -Filter “*current*” -Recurse | Rename-Item -NewName -whatif Run the following Windows PowerShell command:.Assuming we need to find all files located under C:temp (including all subfolders) with “current” in the name and rename them using “old” in place of “current”, here are the steps.
I have never attempted this specific task, but by using Get-Command and Get-Help, we were able to find exactly how to do this in a couple of minutes. For example purposes, let’s say he needed to find all files with “current” in the name and replace “current” with “old”.
He needed to find all files with a specific character string in the name and replace this character string with a new character string. His immediate need was to rename almost 250 files that are located in various folders on the file system. I told him that I am sure Windows PowerShell can help-and that was before I even heard the question. He had a business need and he heard from someone that Windows PowerShell could help. I received a call from a gentleman named Cristofer this afternoon. Matt Tisdale is back today with another solution to a situation at work… Microsoft Scripting Guy, Ed Wilson, is here. Summary: Learn how to use Windows PowerShell to rename files in bulk.
