recurse(dir) do |item|

Find.find is very similar, though it first visits directories and then
their content (preventing to delete directories), and does not change
the current dir.

find #{start} ! -type d.each { |file|
File.delete(file)
}

ksh again :open_mouth:

It might also be good to have an iterator that only
visited directories. But I haven’t thought that through.

find #{start} -type d.each { |dir|
…
}

ksh yet again… :open_mouth:

Why not use ‘find’?

require ‘find’
require ‘ftools’
Find.find( start ) { |file|
File.delete(file) if File.file? file
}

find #{start} -type d.each { |dir|
…
}

Why not use ‘find’? :wink:

Actually, this is a bit more complicated, because Ruby doesn’t have a
recursive unlink:

require ‘find’
require ‘ftools’
dirs =
Find.find( start ) do |file|
if File.file?(file) ; File.rm_f(file)
elsif File.directory?(file) ; dirs << file
end
dirs.sort{ |x,y| y.length <=> x.length }.each{ |d| Dir.delete d }
