替换controlM字符或回车符并将下一行追加到上一行

Question

我有一个像

这样的文件

"A","b","HI This is Bad","End of line1" -- This line1 is good
"A","C","THIS is^M      ------THis line2 is bad.
Good","End of line2"

我需要文件像

"A","b","HI This is Bad","End of line1"
"A","C","THIS is Good","End of line2"

我的文件毕竟还有一些垃圾数据。数据现在看起来像 -

"A","b","HI This is Bad","End of line1" -- This line1 is good
"A","C","THIS is^M      ------THis line2 is bad.
Goo^M
d","End of line2"

所以想想上面可能有多个^ M而不仅仅是1或2.Cyrus给出的解决方案仅适用于1 ^ M.如果我有n ^ M怎么办，我怎么解决这个问题？

Answer 1

sed＆＃39; / \ r $ / {：a; N; $！ba; s / \ r \ n / / g}＆＃39; filename.csv＆GT; filename_final.csv

似乎有效。

基本上创建了一个标签并将其循环
