How to concatenate variables in Perl

Question

Is there a different way to concatenate variables in Perl?

I accidentally wrote the following line of code:

print \"$linenumber is: \\n\" . $linenumb         


        

Answer 1

You can backslash the $ to print it literally:

print "\$linenumber is: \n" . $linenumber;

That prints what you were expecting. You can also use single quotes if you don't want Perl to interpolate variable names, but then the "\n" will be interpolated literally.
