Subject: [ruby-talk:11981] File exist method


Is there a method or a simple way to check
if some file exist?

Something like:

  File.exist? ("myFileName")


One solution to this problem is: 

  ! Dir.entries (".").find { |a| a == "myFileName"}.nil?

But it's not so handy when you are searching other
directories.

A second solution is opening the file and catching
an exception if the file doesn't exist. Although
it works I do not like it because you're violating
the principles behind the proper use of exceptions?

Paul.
