用于将多行连接到分隔符后面的单行的Perl脚本
用于将多行连接到分隔符后面的单行的Perl脚本
提问于 2012-11-09 12:54:26
我正在从远程系统获取消息，响应是多行的，我必须将其转换为基于分隔符的单行。
流阅读器的内容如下
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
:响应的多行应转换为单行，直到分隔符":“
请注意，im从远程系统读取它，而不是从文件读取，它是连续的，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:有没有人能帮我想个办法或命令来实现这个目标？

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
