Renaming all subdirectories using Ruby -

i have nested folder structure on windows 7 machine. windows refuses delete directories names long. want rename subfolders 2 in hope short enough deleted. script:

@count = 0  dir.glob("**/*") |file|  #find src files in current folder , subfolders   if file.directory?(file)     file.rename(file, file.dirname(file) + file::separator + "2")     @count += 1   end end  puts @count 

when script runs, instead of renaming sub-directories, changes 1 more sub-directory, gradually going 1 level deeper each time. i.e., output running script @ moment is:

c:\>renamer.rb 30 c:\>renamer.rb 31 c:\>renamer.rb 32 

i'm confused why happening , appreciate input.

am taking correct approach? assume ruby's recursive directory deletion methods fail. however, when try , execute

require "fileutils" fileutils.remove_dir ("2", force = true) 

i error

syntax error, unexpected ',', expecting ')' fileutils.remove_dir ("2", force = true)                           ^ syntax error, unexpected ')', expecting end-of-input fileutils.remove_dir ("2", force = true)                                     ^ 

the problem dir.glob("**/*") returns array this:

['folder', 'folder/sub', 'folder/sub/sub'] 

now when do:

file.rename(file, file.dirname(file) + file::separator + "2") 

it rename folder, when reaches folder/sub, doesn't exist anymore, because have renamed folder 2: 2/sub instead of folder/sub. solution reverse array. starts renaming process on deepest level , works way top level:

dir.glob("**/*").reverse.each |file|   # rest of code can stay same end 

as second problem, instead of:

fileutils.remove_dir ("2", force = true) 

you should use:

fileutils.remove_dir("2", true) 

first of all, make sure there no space between remove_dir , (. that's what's causing error.

also force name of parameter , default it's false. that's why see force = false in api. if want force true can pass true function, show above.
