Subject: Newbie: Recursive deletion of files and dir

Hi!
I'm designing (newbie level) a script to clean up empty directories and 
old files recursivly. Something is wrong..works fine when not actually 
deleting anything, but when I start removing files and directories it 
ends prematurly.. any heklp available..?

def thisDir(dirname,f)
	Dir.chdir(dirname)
	currDir=Dir.getwd
	nf=0
	nd=0
	fs=0.0

	if Dir.entries(currDir).size>2 then
		Dir.foreach(currDir) {|x|
		if FileTest.file?(x) && (Time.now-File.mtime(x))/(60*60*24)>15 then
			f.puts("deleting file"+x)
			nf=nf+1
			fs=fs+File.stat(x).size
		end
		if FileTest.directory?(x) && x!="." && x!=".." then
			lV=thisDir(x,f)
			nf=nf+lV[0]
			nd=nd+lV[1]
			fs=fs+lV[2]
		end
		}
	Dir.chdir("..")
	end
	if Dir.entries(currDir).size<=2 then
		Dir.chdir("..")
		f.puts("deleteting this directory:"+currDir)
		nd=nd+1
		#Dir.delete(currDir)
	end

	#Dir.chdir("..")
return [nf,nd,fs]
end
outFileName="cleaned-"+Date.today.to_s+".log"
f=File.new(outFileName,"w")
values=thisDir("./",f)
puts "Deleted "+values[0].to_s+" files"
puts "Deleted "+values[1].to_s+" directories"
puts "Total size deleted:"+(values[2]/(1024)).to_s+" kB"

Any advice is appriciated
