Hello,
Can someone please tell me how to get a count for the number of files in
a directory?
Example:
files = Dir.glob("*.pdf")
puts files.count ??
That doesn’t work, but, I’d love to know what would work.
Thanks,
Peter
Hm, that works for me. And so does: Dir["*.pdf"]
I found my answer. Thanks, anyway. It’s “puts files.length.”

You can interrogate “files” as to what it is, and / or what methods it
accepts:
files.class
files.methods.sort
Then you can check Ruby’s documentation (or remember off the top of
your head 
) what other method would be appropriate (if any).

(Ah, how soon!) they forget
When I’ve moved on to some other place,
There may be one or two,
When I’ve played and passed through,
Who’ll remember my song or my face.

It’ll return an Array, which has #size or #length to return the number
of elements in it.
