Proof if a File exsists

[Jonathan Heinen]

Hi,

I want to proof if a File exsist. I just realize this by

if(Dir.glob(file).length == 0)

But I think there should be a better possibiliti like File.exsists?(file)

You're close. Check the docs:

Actually it's File.exist?(file). There's a whole slew of these file
tests, such as File.directory?, File.readable?, File.writable? and so
on. Have a look at the documentation here:
