使用cd命令输入目录：cd MYPATH

$names = (ls).name
foreach ($name in $names) {
    $name_split = $name.split(" ")
    $old_name = $name
    $name = ""
        foreach ($name_part in $name_split) {
            $name_part = $name_part.substring(0,1).toupper()+$name_part.substring(1).tolower()    
            $name += ($name_part + " ")
        }
    Move-Item -Path $old_name -Destination $name.substring(0,$name.length - 1)
}

这应该对你有用。很高兴你认为一些无聊的任务可以用powershell自动化。让我知道它的进展！

应该可以这样做：

$files = @('afghanistan flag.png'
 'aland islands flag.png'
 'peru flag.png')

$files | ForEach-Object {
  $parts = $_ -split " " | ForEach-Object { 
  "$($_.substring(0,1).toupper())$($_.substring(1).tolower())" }
  $newfilename = $parts -join ' '
  Write-Host "This is the new name: $newfilename"
}

输出量：

This is the new name: Afghanistan Flag.png
This is the new name: Aland Islands Flag.png
This is the new name: Peru Flag.png
