【问题描述】：

我有一个带有逗号分隔值的文本文件，其中列值中有换行符。所以它使列数据拆分到下一行导致数据问题。

样本数据

"604","56-1203802","xx","VEN","null","50","1","20","Nï¿½
jTï"
"5526","841328305","yyINC","VEN","null","50","1","20","~R¿½Kï¿½ï
¿½ï¿½}("
"604","561203802","C","VEN",,"null","50","1","20","2ï½aï¿½ï¿½"

预期输出

"604","56-1203802","xx","VEN","null","50","1","20","Nï¿½jTï"
"5526","841328305","yyINC","VEN","null","50","1","20","~R¿½Kï¿½ï¿½ï¿½}("
"604","561203802","C","VEN",,"null","50","1","20","2ï½aï¿½ï¿½"

我需要删除双引号字符串中的换行符。

我尝试了下面的 awk 命令来删除它，但它没有按预期工作。

gawk -v RS='"' 'NR % 2 == 0 { gsub(/\n/, "") } { printf("%s%s", $0, RT) }' infile.txt > outfile.txt

所需的结果是从数据中删除 LF 和 CR 字符。

我为发布的类似问题尝试了解决方案，但对我不起作用。

文件中的换行符是不可见的，除非当它显示为 CR LF 时复制到 Notepad++。

请不要发布数据的图像，我们不会将其输入并用于测试。
@JamesBrown 是的，现在改变了。请看一下
请为示例数据添加代码标签而不是引号。

你可以试试这个sed:

sed ':loop; /" *$/!{N;s/\n//g; b loop}' file
