Perl String Escaping Characters

All the special characters or symbols like @, #, $, & /, , etc does not print in a normal way. They need a preceding escaping character backward slash () to get printed.

Perl Escaping Double quotes

Perl Double-q Operator, qq

The “qq” operator replaces the double quote surrounding a string by its parentheses. It means (“”) are not essential on this string anymore. It will simply print the string with qq.

But if you want a bracket inside a string then you need to use curly braces {} surrounding the string.

And if you need curly braces inside the string then use square bracket [] surrounding the string.

Output:

Our site "tutoraspire" provides all type of "tutorials"  Our site (tutoraspire) provides all type of "tutorials"  Our site (tutoraspire} provides all type of "tutorial"  

Perl Single-q Operator, q

The single ‘q’ operator works as the single quote (‘) in the string. Like single quote, it also does not interpolate the variables.

Output:

Our site "tutoraspire" provides all type of "$x"n  Our site "tutoraspire" provides all type of "$x" n  Our site )tutoraspire( provides all type of "$x" n  Our site )tutoraspire} provides all type of "$x" n
