Join Kevin Skoglund for an in-depth discussion in this video Glob, part of Ruby: Files, Formats, Templates.
- [Instructor] In this movie we're going to learn…about another way that we can access the contents…of directories using something called Glob.…It's a very strange name.…What Glob does is returns an array of file names…which match a pattern.…So unlike entries, that just return everything…that's in the directory, this allows us to use a pattern…to match certain entries.…The patterns are similar to globs in the Unix shell.…That's where the name actually comes from for this method…is from Unix shell where they have globs.…
Basically a Glob is like a very primitive version…of regular expressions.…It doesn't have all the power and all the tools…that are built into regular expressions,…but we do have some basic pattern matching that we can do.…Let's look at the simplest version first.…Here I'm using the dir class, and I'm calling…the Glob class method on that.…And I'm passing in the pattern that I want to match for.…The asterisk is the most simple one there is,…because it's just a wild card.…Basically it says match everything.…
