Newbie: Recursive deletion of files and dir

Ruby
1

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

I did not read this code yet but take a look at ri FileUtils,
it has useful methods including two that might be handy here:

FileUtils.rm_rf
FileUtils.mkdir_p
