Subject: Re: working with file types and directories

OK, next step...
I can now run tests on files within directories. How can I achieve
something like the following?

 puts "files have been checked" if  Dir.foreach(".") {|x| puts
FileTest.writable?(x) } == "true"

#at the moment I get this:-
irb(main):022:0> puts "files have been checked" if  Dir.foreach(".")
{|x| puts FileTest.writable?(x) } == "true" true
true
true
true
true
true

#but *not* the desired string "files have been checked"
