回车与换行
- \r = CR (Carriage Return) → Used as a new line character in Mac OS before X
- \n = LF (Line Feed) → Used as a new line character in Unix/Mac OS X
- \r\n = CR + LF → Used as a new line character in Windows
在vim中, \n是匹配行结束, \r是匹配回车符. 插入中, \n是插入null字符(^@), \r是插入
回车CR. 所以要把字符替换成换行, 需要%s/a/\r/g
打开特殊字段匹配(可以匹配^@之类), :set magic
- NUL == 0x00 == 0 == Ctrl + @ == ^@ shown in vim
- LF == 0x0A == 10 == Ctrl + J
- CR == 0x0D == 13 == Ctrl + M == ^M shown in vim
