Hi,  
what’ s the best way to detect if a Dir entry is a directory or file? I’  
m doing a Dir.foreach blabla |x|.  
I’ m trying to use ‘directory?’, but it doesn’ t work the way I use it.

Thanks,  
Alex.

Dir.foreach yields just basenames. You’ll need to prefix the  
directory name to them.

Dir.foreach(blabla) {|x| x = File.join(blabla, x); p x if  
File.directory?(x)}

Or, Dir.glob(File.join(blabla, “\*/”)) returns an array of the  
directories.

Thanks,  
it works. I just offered names to the ‘directory?’-method.

Dir.new(’./’).entries.partition {|i| File.directory?(i))}  
=\> [  
[".", “…”, “log”, “src”, “conf”, “\_darcs”, “public”, “script”,  
“templates”],  
[“README”, “run.rb.save”, “run.rb”]  
]
