Hi!  
I’ve been stuck with simple thing - I’m trying to change dir into not  
existant directory. I’m using following code:

dir=“no\_such\_one”  
begin  
Dir.chdir(dir)  
rescue  
into\_dir = false; #we didn’t make it  
end

And resuce does not catch this:

Exception `Errno::ENOENT’ at ./test.rb:33 - No such file or directory -  
no\_such\_one

But Errno::ENOENT is child of StandardError, which should be catched by  
default. So I’m probably making some stupid mistake - but I can not find  
what one. Could someone help me?

OK to be clear - execution is not stopped at this point (so resue is  
somehow working) but I was not expecting this message on stderr. How to  
get rid off this message?

Seems like a message displayed when $DEBUG is turned on.
