How to check for file existence [duplicate]

Is there a Ruby class/method where I could pass "a full path", home/me/a_file.txt, to identify whether it is a valid file path?

# file? will only return true for files
File.file?(filename)

and

# Will also return true for directories - watch out!
File.exist?(filename)

Check out Pathname and in particular Pathname#exist?.

File and its FileTest module are perhaps simpler/more direct, but I find Pathname a nicer interface in general.
