Hey!

How do i check if a file exists, that starts with a certain identifier?

e.g. Files in Directory

file_1.rb
file_2.rb
test_1.rb

I only want to know if a file exists, that starts with "file_"

thx

Dir.entries('.').detect {|f| f.match /^file_/}

Replace '.' with the name of the directory to check if it is not the
current directory. Will return the name of the first file to match if
there is one, else will return nil.

Rev B includes a wire harness needed for Stern's newer games (they cut out a
small chunk of wire that lead from the back to the front of the cabinet).
