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

I like .= operator method:

#!/usr/bin/perl
use strict;
use warnings;

my $text .= "... contents ..."; # Append contents to the end of variable $text.
$text .= $text; # Append variable $text contents to variable $text contents.
print $text; # Prints "... contents ...... contents ..."
