我在 macOS 上有一个由 Windows 创建的 CSV 文件，如下所示：

"C00115940","","","","","O","","","f","","b",NULL,"92583","","123-456-7890","","","","","","M","W","","","","jc@abc.def","","","","C","5","","S",NULL,"92583","","951","","","m@s.gov","","","","","","","","","",NULL,NULL,"",NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,"",NULL,NULL,"",NULL,NULL,"",NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,"",NULL,NULL,"",""," ","1","",NULL,"","","","","",NULL,"","75350","","","",NULL,"","","","","","","","","","",""¬
"C00102747","","","","","R","","","3","","A",NULL,"12207","","5","","","","","","S","D","","","","t@abc.def","","","","R","35 Any St¬
3rd Fl","","A",NULL,"12207","","5","","","S@r.org","","","","","","","","","",NULL,NULL,"",NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,"",NULL,NULL,"",NULL,NULL,"",NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,"",NULL,NULL,"",""," T","1","",NULL,"","","","","",NULL,"","75350","","","",NULL,"","","","","","","","","","",""¬

在 vim 中，我启用了 :set list，因此您可以看到 ¬ 换行符所在的位置。

在第二行中，我需要删除的一个字段中间有一个换行符。每行应始终以双引号结尾。如果我执行/[^"]$，例如，我可以在第二行看到t¬，其中换行符位于地址字段内（"35 Any St¬ 3rd Fl"）

我已经尝试过:%s/$[^"]$$/\1/g，但没有任何作用。

我可以运行更好的替换命令来删除这些错误的换行符，但不会删除其他任何换行符吗？

你已经接近了！您可以使用\n 匹配vim 搜索命令中的新行，所以您可以使用以下方法突出显示有问题的行：

/[^"]\n

你可以像这样加入他们：

:%s/\([^"]\)\n/\1/g

或者以更优雅的方式使用全局命令：

:g/[^"]\n/join

或等效：

:g/[^"]\n/normal J
