批量文件重命名 - PowerShell

Question

我在这种格式的文件夹中有很多文件

constant_blah_blah_blah.png

如何使用空格替换下划线，并使用PowerShell从中删除constant_？

提前致谢。

Answer 1

你可以试试这个

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

Answer 2

# 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 '_', ' ')
   }

或更短：

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