Cmd/Powershell 好用指令

• 批次更改目錄中檔案名稱
  Get-ChildItem -Filter Pattern | Rename-Item -NewName {$_.Name -replace 'keyword1','keyword2'}
  
  
• 取得目錄下符合Pattern (如*.txt) 的檔案，將檔名中的關鍵字keyword1替換成keyword2。
  
  
• 指令中的$_代表當前Pipeline的輸入對象，其中需要注意的是keyword1中若有符號需以 \ 跳脫，keyword2不用。
  
  
• 合併目錄中CSV檔案
  for /f %a in ('dir /b *.csv') do for /f "tokens=*" %b in (%a) do echo %b,%a >> output.csv
  
  
1. for /f %a in ('dir /b *.csv') do
   進入迴圈，接收 dir /b *.csv 的每一列輸出結果(檔案名稱)並分配給變數 %a，執行後續指令。
   
   
2. for /f "tokens=*" %b in (%a) do
   進入迴圈，將 %a 檔案裏的每一列內容分配給 %b 變數，執行後續指令。
   
   
3. echo %b,%a >> all.csv
   輸出變數 %b、逗點與變數 %a 至 output.csv 檔案中
