Defining strings and newlines in perl
The declaration below indicates two different characters, \ and an n.
$string = '\n';
Declaring literal with single quotes
$string = 'Jon \'Main\' Deva';
Double quotes interpolate variables and expand a lot of backslashed shortcuts: \n becomes a newline, \033 becomes the character with octal value 33, \cJ becomes a Ctrl-J, and so on.
$string = "\n"; # a "newline" character $string = "Jon \"Main\" Deva"; # literal double quotes
