PowerShell Implement batch rename file _powershell

If you have a large folder with pictures in it and you want to rename the picture in the folder according to a uniform rule, the script for this article will be simple to demonstrate:

$i = 0
 
get-childitem-path c:\pictures-Filter *.jpg |
Foreach-object {
$extension = $_. Extension
$newName = ' pic_{0:d6}{1} '-f $i, $extension
$i + +
Rename-item-path $_. Fullname-newname $newName
}

All of the JPG files in the folder have been renamed, and the new picture filename is shaped like "pic_" and a 6-digit number, and you can make a few modifications to this template to complete a richer custom rule.

Small note: When I was still using padleft and padright, I found that the original string formatting parameters were already supported.
