如何删除像*，\ xC2 \ xA02003 \ xC2 \ xA02004 \ xC2 \ xA0这样的字符，以及最后一行可能会在Scala处理中抛出错误的空行。我需要维护CSV结构以与以前相同的方式，但要求删除这些。
请帮我在shell脚本中实现这个目的？ 再次感谢您，因为我是shell脚本的新手

请告诉我如何纠正损坏的行（没有'，'），如

答案 0 :(得分：2)
您可以使用sed，但我很确定，您可能无法获得100％的结果。您应该使用您正在处理的文件的本机工具来获得所需格式的结果。无论如何，下面是我的尝试：
$ sed -E '/^[^,]*$/d;/^[0-9]+, *$/d;s/ \*+ */ /;s/\\[xX][^\ ,]*//g' case_file_48246326
