Like any programming language, Perl uses special commands for special characters, such as backspaces or vertical tabs. So, if you need to program in a bell or a beep or just a carriage return, check the following table for the character that will produce it:

Character Meaning
\n Newline
\r Carriage return
\t Tab character
\f Formfeed character
\b Backspace character
\v Vertical tab
\a Bell or beep
\e Escape character
