我已成功使用反转匹配来过滤/*和*/之间的字符串这是我的bash输出：

/ ZoeLabs / - [ moono ] > sed -n '/\/\*/,/\*\//!p' example.css
http://www.example.com



http://www.example2.com/ ZoeLabs / - [ moono ] >

我希望输出

/ ZoeLabs / - [ moono ] > sed -n '/\/\*/,/\*\//!p' example.css
http://www.example.com



http://www.example2.com
/ ZoeLabs / - [ moono ] >

但是，为什么sed在newline之类的匹配模式之后没有追加awk呢？我该怎么做才能追加它？

Answer 1

sed ':a;$!N;$!ba;s/\/\*[^*]*\*\([^/*][^*]*\*\|\*\)*\///g' example.css|awk '{print}'

为什么sed没有像awk那样添加换行符？
