Removing comments and blank lines takes two commands. The first removes every character from the "#" to the end of the line,and the second deletes all blank lines: sed -e 's/#.*//' -e '/^$/ d' A third one should be added to remove all blanks and tabs immediately before the end of line: sed -e 's/#.*//' -e 's/[ ^I]*$//' -e '/^$/ d' （编辑：晋中站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
