A Mini Perl Escape Tutorial
December 8th, 2009
I wrote an article for my website on “Escape Sequences in Perl Statements”. Now I know that’s really exciting news, so I thought I would tell you a bit more about my perl escape tutorial. First of all, what exactly IS an escape sequence? It’s a character preceded by a backslash ( \ ). What’s the backslash for? It’s to tell the Perl interpreter that the next character is NOT to be interpreted as a metacharacter. In other words, it’s to be interpreted in its literal sense. For example, \$ means that the $ stands for a dollar sign, not the start of a Perl variable name. I hope all that was clear. There will be a quiz next session.
