如何摆脱引号之间的逗号？引号之间也有不带逗号的行。

我需要删除里面的逗号"JUDICIARY, STATE COURTS (STATE COURTS)"（两行都出现在一行）。

这是一个演示如何操作的脚本 - 欢迎来到goto sed的世界。这是使用BSD sed编写的，它使用-E来启用扩展正则表达式; GNU sed使用-r执行相同的任务。

sed -E -e 's/^/A: /p; s/^A: /B: /' \
       -e ':again' \
       -e 's/^(([^"]*|"[^",]*")*)("[^"]*),([^"]*")/\1\3\4/' \
       -e 't again' \
       data

假设数据位于名为data的文件中。第一个-e只是回显前缀为A:的原始输入，然后将前缀更改为B:。这是调试材料。第二个-e生成一个可以跳转的标签again。如果上一步做了替换，则第四个-e会跳转到again标签。

所有的兴奋都在第三个-e。该模式寻找行的开始，然后是一系列零序或多次出现的序列 “不是双引号”或“双引号后跟零或更多'不是双引号'和双引号”，后跟双引号，一系列'不是双引号，逗号，更多'不是双引号'和a双引号。这被前缀替换，双引号之间的逗号前面的部分和双引号之间的逗号之后的部分。

给定一个数据文件：

2000,"xxxx,xxxx",192.168.3.2
2000,"xx,xx,xx",192.16.3.2
2000,"xxxxxxxx",192.168.3.2
20000000,"xxxxxxxxxxxx,xxxxxxxxxxxx",192.168.3.2,"yyyyy,yyyyy"
20000000,"xxxxxxxxxxxxx,xxxxxxxxxxx",192.168.3.2
20000000,"xxxxxxxxxxxxxxxxxxxxxxxx",192.168.3.2
201,"x,x",192.168.3.2,"y,y","aaaa,cccc,dddd",192,"zzzz",234
201,"x,x",192.168.3.2,"yyy"
201,"xx",192.168.3.2,"yyy",2211
201,"xxx",192.168.3.2,"y,y"
201,"xxx",192.168.3.2,"yyy"
201,"x,x",192.168.3.2,"y,y"

请注意：这很难。如果您有选项，请使用知道CSV格式的工具。例如，Python附带一个CSV模块; Perl有Text::CSV（以及辅助模块Text::CSV_PP和Text::CSV_XS）可以处理这个问题;有一些用于处理CSV文件的自定义工具。

另请注意，Microsoft支持与RFC 4180略有不同的表示法，这是互联网世界试图合理化Microsoft使用的内容（初步估算）。
