我有一个CSV文件，除非在字符串中，否则只想删除所有引号。
示例：
"I have a file that says "need help" please"
除非在双引号内，否则我想删除文本中的所有双引号。例如，不要删除“需要帮助”周围的引号
任何人都有线索？
我在awk和sed命令方面做得非常好，但这个让我很难过。
感谢您的帮助！

根据您的CSV格式和要求，这可能会也可能不会达到您想要的效果：
$ cat file
"I have a file that says "need help" please"
"a "b" c","d "e" f"
$
$ awk -F'","' -v OFS=, '{$1=$1;gsub(/^"|"$/,"")}1' file
I have a file that says "need help" please
a "b" c,d "e" f

使用grep -Po '".*?"'：
echo 'this is a test "I need help" and "it has to be now"' | grep -Po '".*?"'
"I need help"
"it has to be now"
