Hi all, I'm brand new to ruby, and I'm looking for a way to open a file, read its content and modify it. I've seen that I can open a file in read write mode, but I can't figure out how it works. If I want to replace all occurences of 'search' by 'replace', for instance, what do I have to do? Searching for an answer to this question, I've found scripts using gsub! What is this exclamation mark? Thanks in advance for your help! Xavier -- Posted via http://www.ruby-forum.com/.
