Regular expressions

ruby-talk
1

I'm writing a script that is looking through a file for the following
lines

*something*

and replacing it with

*something* - info about the something

my problem is that I can't find info about searching for the "*"
character.

I've been reviewing the regular expression docs and can only find the
usage for "*" and not how to search for *#{stuff}*

any help would be great.

* is a special character for regular expressions, so you have to escape it:

/\*something\*/

Regexp.escape("*something*") is handy too.
