推荐答案

嗨Rajiv，


你必须提供更多关于你要做什么的细节..但我想你应该去寻找与正则表达式匹配的模式。

Hi Rajiv,

You have to provide more details about what you are trying to do.. But I guess you should go for pattern matching with regular expressions.

谢谢你mehj123


让我解释一下。我有一个文件有一组名称和年龄。所以我有一个输入名称''Rajiv''如果它在文件的任何一行匹配，我想编辑该行到其他一些细节。


但我使用Tie :: File Module解决了这个问题。
