Question

我从远程系统收到消息，响应是多行的，我必须根据分隔符将其转换为单行。

流阅读器的内容如下所示

Iam in first Line
Iam in second Line
:

Iam in third Line
Iam  in the forth Line
Iam in fifth Line
:

Iam in Sixth Line
Iam In seventh Line
IAm in Eighth Line
:

应将多行响应转换为单行，直到分隔符“：”

请注意我从远程系统读取它，而不是从文件中读取它，它连续并且没有eof.until与远程系统的连接终止

输出应为：

Iam in first Line Iam in second Line:
Iam in third Line Iam in the forth Line:
Iam in Sixth Line Iam In Seventh Line Iam in Eighth Line:

有人可以帮助一个方法或命令来实现这个目标吗？

$ perl -pne 'chomp unless(/^:/);' file

Answer 2

perl -p -e 's/\n/ /g;s/:[\s]*/:\n/g' your_file

测试如下：

> cat temp
Iam in first Line
Iam in second Line
:

Iam in third Line
Iam  in the forth Line
Iam in fifth Line
:

Iam in Sixth Line
Iam In seventh Line
IAm in Eighth Line
:
> perl -p -e 's/\n/ /g;s/:[\s]*/:\n/g' temp
Iam in first Line Iam in second Line :
 Iam in third Line Iam  in the forth Line Iam in fifth Line :
 Iam in Sixth Line Iam In seventh Line IAm in Eighth Line :
