This brief script *replaces* the batch search-and-replace tool in your commercial text editor. If batch file search and replacement is the only reason you need an IDE, you can adopt this script and go back to using Notepad (or better yet `vi`). Thanks to JPinyan, who taught me the pattern shown below, back in 2001 on `beginners.perl.org` The regular expression flags used here are explained in excellent detail in the *best practices for regular expressions* chapter of **Perl Best Practices** by Damian Conway.

(Ruby) Update RubyGems to the latest version (how to upgrade the gem command)

Mon, 20 Oct 2008 12:02:19 GMT

This command tells RubyGems to upgrade _itself_ to the latest version of RubyGems. **Updated 2010** on modern RubyGems, all you have to do is gem update --system and you are set. Then you can say `gem update` to get the latest versions of installed gems. The rest of this post will be left intact for historical purposes. ## If you were going to read the documentation… …then remove `--no-rdoc` and/or `--no-ri`. ## If you also want to update all installed gems… …then just say `sudo gem update`
