Forum: Ruby Is there any difference between Dir::exist? and Dir::::exists?

Hi,


I am confused with the below Dir class methods:

Dir::exist?
Dir::::exists?

Can anyone help me here to understand the difference between them with
an simple example?


Thanks

"Dir::::exists?" doesn't exist.

exists? and exist? are aliases, I think.

Personally I use File.directory?

That is a syntax error.  I guess you mean Dir::exists?.

Why do you assume there is a difference?  Did you read the 
documentation?  Hint:

$ diff -U5 <(ri -T Dir::exist?) <(ri -T Dir::exists?)

   File.directory?(file_name)   ->  true or false
