From: Kevin Austin on 26 Apr 2010 13:28 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. -- Posted via http://www.ruby-forum.com/.
