如何去除双引号中的新线路？ [英] How to remove new lines within double quotes?

问题描述

我怎么可以删除里面的新行从一个文件？

How can I remove new line inside the " from a file?

例如：

"one", 
"three
four",
"seven"

所以我想删除 \\ n 之间的三和四。我应该使用常规的前pression，或者我要读这是每个字符的文件与程序？

So I want to remove the \n between the three and four. Should I use regular expression, or I have to read that's file per character with program?

推荐答案

要处理特别是那些在双引号字符串换行符，离开那些单独是他们之外，使用GNU AWK（为 RT ）

To handle specifically those newlines that are in doubly-quoted strings and leave those alone that are outside them, using GNU awk (for RT):

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

这工作沿着字符和删除换行符隔挡，随着包含文件

This works by splitting the file along " characters and removing newlines in every other block. With a file containing

"one",
"three
four",
12,
"seven"

这会给结果

"one",
"threefour",
12,
"seven"

请注意，它不处理转义序列。如果输入的数据字符串可以包含 \\，如他说：\\这是一个直接引用\\。，那么它将无法获得理想的工作。

Note that it does not handle escape sequences. If strings in the input data can contain \", such as "He said: \"this is a direct quote.\"", then it will not work as desired.
