: LF = \n - On classic versions of macOS [1][2] e.g. Mac OS 9: CR = \r
如何看到換行符號
查看每一行使用的換行符號
- Notepad++ On Win 選單: 檢視: 特殊字元: 顯示行尾字元 (EOL)
查看檔案使用的換行符號
- file (command): file filename.txt on Linux , macOS [3] & Cygwin on Win
| 檔案內容 | File command 偵測結果 |
|---|---|
| 換行符號是 CRLF = \r\n | UTF-8 Unicode text, with CRLF line terminators |
| 換行符號是 LF = \n | UTF-8 Unicode text  |
| 換行符號是 CR = \r | UTF-8 Unicode text, with CR line terminators |
| 換行符號夾雜 \r\n 和 \r | UTF-8 Unicode text, with CRLF, CR line terminators |
| 換行符號夾雜 \r\n 和 \n | UTF-8 Unicode text, with CRLF, LF line terminators |
