def find\_controller\_names  
a = []  
Find.find( RAILS\_ROOT + ‘/app/controllers’ ) do |file\_name|  
if /.rb$/ =~ file\_name  
a \<\< File.basename(file\_name).gsub(’.rb’, ‘’).camelcase  
end  
end  
render\_text a.inspect  
end

if you run find\_controller\_names, you’ll get something like  
[“Application”, “SomeController”, “OtherController”]

hope it helps!  
🙂
