Question

I am a beginner of perl scripting.
I know hyphen (-) is used to specify the range.

But what if it is mentioned in the beginning of the expression?

Example:

if ($_ =~ /-\n/)
//do something

How to interpret the above code?

“if the parameter is equal to a range of newline” ?
(No, that is weird understanding :-/)

Please help.

Answer 1

This means:

If there is a hyphen immediately followed by a newline-character, no matter where this pair of characters is located inside the string.
