批量文件重命名- PowerShell

Question

我在一个文件夹里有很多这样格式的文件

constant_blah_blah_blah.png

我如何用空格替换下划线，并使用PowerShell删除常量_ ?

Answer 1

# gather all files that match the criteria
Get-ChildItem constant_* |
   ForEach-Object {
      # remove the "constant_" from the beginning and replace _ by space.
      Rename-Item $_ ($_.Name -replace '^constant_' -replace '_', ' ')
   }

或短:

ls constant_* | %{rni $_ ($_.Name -replace '^constant_' -replace '_', ' ')}

Answer 2

你可以试试这个

Get-childItem constant* | % {rename-item $_.name ($_.name -replace '_',' ')}
Get-childItem constant* | % {rename-item $_.name ($_.name -replace 'constant ','')}
