[文件操作] [已解决]批处理怎么在文件/文件夹名中按要求加入某个字符？

<#*,:&cls
@echo off
pushd "%~dp0"
powershell -NoProfile -ExecutionPolicy RemoteSigned -Command ". ([ScriptBlock]::Create((Get-Content -LiteralPath \"%~0\" -ReadCount 0 | Out-String ))) "
popd
pause
exit /b
#>
# 文件名 2个及以上字母与2个及以上数字之间添加-
Get-ChildItem -Path . -Filter * | ForEach-Object {
  $newName = $_.FullName -replace '(?<=[a-z]{2,})(?=[0-9]{2,})|(?<=[0-9]{2,})(?=[a-z]{2,})', '-'
  if ($newName -ne $_.FullName) {
    Rename-Item -LiteralPath $_.FullName -NewName $newName -Force -Verbose
  }
}
