Checking for file existance

Hi,

How do I check if a file (possibly a directory) exists? This is probably

easy, but I was not able to find it.

Thanks,

It’s kinda hard to find - the FileTest object is what you’re looking for

The method ‘exists?’ can tell you if it exists…

The method ‘file?’ can tell you if it’s a file…

The method ‘directory?’ can tell you if it’s a directory…

But I use

returnedString = File.ftype (“nameOfFile_or_directory”)

Which returns strings like - ``file'', ``directory'',

characterSpecial'', blockSpecial’‘, fifo'', link’‘, or ``socket’'.
(taken from the Ruby help files…)

File.exist?(“filename”)
