在替换对话框中，您要将搜索模式设置为“扩展”。正常或正则表达式模式不工作。

然后只需要找到"\r\n"(对于unix文件只需要\n，对于mac格式文件只需要\r)，然后将替换值设置为你想要的任何值。

我在NP v6.9中完全无法做到这一点。 我发现用微软的Word (2K)软件就足够简单了。

打开文档，点击编辑->replace。

然后在搜索框的底部，点击“更多”，然后找到“特别”按钮，他们有一些东西给你。对于Dos样式，我使用“段落”样式。这是一双橱窗里的cr。

我在查找/替换窗口中使用\r\n个正则表达式时运气不太好。

然而，这适用于notepad++ v4.1.2:

Use the "View | Show end of line" menu to enable display of end of line characters. (Carriage return line feeds should show up as a single shaded CRLF 'character'.) Select one of the CRLF 'characters' (put the cursor just in front of one, hold down the SHIFT key, and then pressing the RIGHT CURSOR key once). Copy the CRLF character to the clipboard. Make sure that you don't have the find or find/replace dialog open. Open the find/replace dialog. The 'Find what' field shows the contents of the clipboard: in this case the CRLF character - which shows up as 2 'box characters' (presumably it's an unprintable character?) Ensure that the 'Regular expression' option is OFF.

现在您应该能够根据需要进行计数、查找或替换。

这似乎是一个常见问题，提供的解决方案是:

Simple search (Ctrl+H) without regexp You can turn on View/Show End of Line or view/Show All, and select the now visible newline characters. Then when you start the command some characters matching the newline character will be pasted into the search field. Matches will be replaced by the replace string, unlike in regex mode. Note 1: If you select them with the mouse, start just before them and drag to the start of the next line. Dragging to the end of the line won't work. Note 2: You can't copy and paste them into the field yourself. Advanced search (Ctrl+R) without regexp Ctrl+M will insert something that matches newlines. They will be replaced by the replace string.

使用高级搜索选项(Ctrl + R)并使用键盘快捷键CRLF (Ctrl + M)插入回车符。
