How can a string be regex ''escaped''? ie. If I had a variable $foo which receives input from stdin. The arbitry character sequence ''[abc]'' is received. How can I escape this string so that it can be used in a regex expression as literal characters and not interpreted as a regex.

two options:

1. the built in function quotemeta();

2. use \Q \E inside the regex, e.g.:

$foo =~ /\Qescaped input is here\E/

If you use perl, you should check out perlmonks.org. Chances are, any question you have has been asked before: see what I mean?
